Subject: [PATCH] f2fs: bugon w/ SBI_NEED_FSCK when has CONFIG_F2FS_CHECK_FS

The SBI_NEED_FSCK flag usually means that the data in the
file system is abnormal, and the fsck tool needs to be used.
When CONFIG_F2FS_CHECK_FS is enabled, let us trigger bug_on
at the first moment when SBI_NEED_FSCK is set, so as to
analyze the first scene.
