Murad Masimov f6fae70f83 ocfs2: fix possible memory leak in ocfs2_finish_quota_recovery 
[ Upstream commit cdc3ed3035 ]

If ocfs2_finish_quota_recovery() exits due to an error before passing all
rc_list elements to ocfs2_recover_local_quota_file() then it can lead to a
memory leak as rc_list may still contain elements that have to be freed.

Release all memory allocated by ocfs2_add_recovery_chunk() using
ocfs2_free_quota_recovery() instead of kfree().

Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
