ext4: enable the lazy init thread when remounting read/write
commit eb1f822c76beeaa76ab8b6737ab9dc9f9798408c upstream.
In commit a44be64bbecb ("ext4: don't clear SB_RDONLY when remounting
r/w until quota is re-enabled") we defer clearing tyhe SB_RDONLY flag
in struct super. However, we didn't defer when we checked sb_rdonly()
to determine the lazy itable init thread should be enabled, with the
next result that the lazy inode table initialization would not be
properly started. This can cause generic/231 to fail in ext4's
nojournal mode.
Fix this by moving when we decide to start or stop the lazy itable
init thread to after we clear the SB_RDONLY flag when we are
remounting the file system read/write.
Fixes a44be64bbecb ("ext4: don't clear SB_RDONLY when remounting r/w until...")
