resolves: bz2003832
conflict:
function remove_kdump_kernel_key() not presented in rhel9,
so related patch hunk are removed.

bash scripts: fix variable quoting issue
Fixed quoting issues found by shellcheck, no feature
change. This should fix many errors when there is space
in any shell variables, eg. dump target's name/path/id.
False positives are marked with "# shellcheck disable=SCXXXX", for
example, args are expected to split so it should not be quoted.
And replaced some `cut -d ' ' -fX` with `awk '{print $X}'` since cut
is fragile, and doesn't work well with any quoted strings that have
redundant space.
Following quoting related issues are fixed (check the link
for example code and what could go wrong):
