[ Upstream commit 682756827501dc52593bf490f2d437c65ec9efcb ]
Even though online resize is successfully done, a SPO immediately after resize, still causes below error in the next mount.
[ 11.294650] F2FS-fs (sda8): Wrong user_block_count: 2233856 [ 11.300272] F2FS-fs (sda8): Failed to get valid F2FS checkpoint
This is because after FS metadata is updated in update_fs_metadata() if the SBI_IS_DIRTY is not dirty, then CP will not be done to reflect the new user_block_count.
