ufs: fix sun state

ufs: fix sun state

Different types of ufs hold state in different places, to hide complexity
of this, there is ufs_get_fs_state, it returns state according to
"UFS_SB(sb)->s_flags", but during mount ufs_get_fs_state is called, before
setting s_flags, this cause message for ufs types like sun ufs: "fs need
fsck", and remount in readonly state.
