btrfs: fix NULL pointer dereference in do_abort_log_replay()
[ Upstream commit 530e3d4af566ca44807d79359b90794dea24c4f3 ]
Coverity reported a NULL pointer dereference issue (CID 1666756) in
do_abort_log_replay(). When btrfs_alloc_path() fails in
replay_one_buffer(), wc->subvol_path is NULL, but btrfs_abort_log_replay()
calls do_abort_log_replay() which unconditionally dereferences
wc->subvol_path when attempting to print debug information. Fix this by
adding a NULL check before dereferencing wc->subvol_path in
do_abort_log_replay().
Fixes: 2753e4917624 ("btrfs: dump detailed info and specific messages on log replay failures")
