From: Chao Yu <chao@kernel.org>

[ Upstream commit a798ff17cd2dabe47d5d4ed3d509631793c36e19 ]

During gc_data_segment(), if inode state is abnormal, it missed to call
iput(), fix it.

Fixes: b73e52824c89 ("f2fs: reposition unlock_new_inode to prevent accessing invalid inode")
Fixes: 9056d6489f5a ("f2fs: fix to do sanity check on inode type during garbage collection")
