[PATCH 15/24] Eliminate shellcheck SC2295 warnings

[Coiby Xu]

Fix the following shellcheck SC2295 warnings,
    In kdump-lib.sh line 177:
            _path=${1#$_mnt}
                      ^---^ SC2295 (info): Expansions inside ${..} need to be quoted
separately, otherwise they match as patterns.

    Did you mean:
            _path=${1#"$_mnt"}

    In kdump-lib.sh line 194:
            _fsroot=${_src#${_src_nofsroot}[}
                           ^--------------^ SC2295 (info): Expansions inside ${..} need to
be quoted separately, otherwise they match as patterns.

    Did you mean:
            _fsroot=${_src#"${_src_nofsroot}"[}

    In kdump-lib.sh line 203:
                    _fsroot=${_fsroot#$_subvol}
                                      ^------^ SC2295 (info): Expansions inside ${..} need
to be quoted separately, otherwise they match as patterns.

    Did you mean:
                _fsroot=${_fsroot#"$_subvol"}
