kdump-lib.sh: introduce two functions abstracted from get_block_dump_target for reuse

Browse Source 
In function get_block_dump_target(), code block to get user configured
dump disk and get root fs device can be reused by other places. Now
abstract and wrap them into 2 new functions:

get_user_configured_dump_disk()
get_root_fs_device()

And put them into kdump-lib.sh.

Meanwhile change the get_block_dump_target() accordingly.
