Subject: [PATCH 4.19 013/149] f2fs: fix to recover inodes i_gc_failures during POR

From: Chao Yu <yuchao0@...wei.com>

[ Upstream commit 7de36cf3e4087207f42a88992f8cb615a1bd902e ]

inode.i_gc_failures is used to indicate that skip count of migrating
on blocks of inode, we should guarantee it can be recovered in sudden
power-off case.
