[COVERITY] Fix missing return code check for ext2fs_write_inode
Found 2 of the three places where a return code for ext2fs_write_inode() was
not being checked.
The second fix in e2fsck/emptydir.c is basically just to shut coverity up even
though it really is unnecessary.

[COVERITY] Fix bad error checking for NULL parameter in ss library
Looks like flawed reasoning. Here if info_dir is NULL then you are
guaranteed to blow up since you will dereference it. It seems like the
correct thing to do here (what the code author meant to do) was to set
*code_ptr = SS_ET_NO_INFO_DIR if info_dir was NULL or if *info_dir was
an empty string (aka *info_dir == '\0').

[COVERITY] Check for NULL return from dict_lookup() in e2fsck
The dict_lookup() function can potentially return a NULL dnode_t. It is
not checked in two places in the clone_file() function. Looks to be
safe to continue if n is NULL, so just print a warning message and
continue.

[COVERITY] Add missing NULL check to e2fsck_get_dir_info()
It is possible that e2fsck_get_dir_info() returns a NULL pointer.
We do not want to blow up when dereferencing p. It seems to be
more sane/safe to call fix_problem(ctx, PR_3_NO_DIRINFO, pctx)
if p is NULL at this point since we do not have any DIRINFO
for pctx->ino.
Also fix another (already existing) error check for
e2fsck_get_dir_info() later in the function so that it reports the
correct inode number if the dirinfo information is not found for
p->parent.
(Both of these are "should-never-happen" internal e2fsck errors that
would indicate a programming bug of some kind.)

[COVERITY] Fix memory leak in libss (ss_execute_line)
Fix a memory leak by freeing the argv[] array if ss_parse_line returns 0
for argc 0 (which will happen if the user his return and sends an empty
line to the application).
Potentially need to free argv before early return since it was allocated
memory. Need to be careful since it may be possible for ss_parse() to have
freed the memory allocated to it if it detects an unbalanced set of quotes
passed to it.

[COVERITY] Fix memory leak in fsck on error paths
The memory allocated by inst is not reclaimed. There also was a
call to exit that coverity did not catch the resource leak. This
might not really be a big issue since the memory will be freed when
fsck exits, but it should be done anyway imho.
