Konstantin Belousov d66ba37013 Fix livelock that could occur when snapshoting UFS with quotas, where
some quota limit was exceeded. Sequence of UFS_VALLOC()/UFS_VFREE()
call there could cause inodeblock to have both freefile and inodedep
dependencies without any inode in the block being marked for write.
Then, softdep_check_suspend() would return EAGAIN forewer.

Force write of inodeblock with allocated freefile softdependency by
setting IN_MODIFIED flag in softdep_freefile and unconditionally calling
UFS_UPDATE() in ufs_reclaim.
