ubifs: Add missing iput if do_tmpfile() failed in rename whiteout
commit 716b4573026bcbfa7b58ed19fe15554bac66b082 upstream.
whiteout inode should be put when do_tmpfile() failed if inode has been
initialized. Otherwise we will get following warning during umount:
UBIFS error (ubi0:0 pid 1494): ubifs_assert_failed [ubifs]: UBIFS
assert failed: c->bi.dd_growth == 0, in fs/ubifs/super.c:1930
VFS: Busy inodes after unmount of ubifs. Self-destruct in 5 seconds.
Fixes: 9e0a1fff8db56ea ("ubifs: Implement RENAME_WHITEOUT")
