[PATCH 5/7] xfs: get quota inode from mp & flags rather than dqp

[Eric Sandeen <sandeen@xxxxxxxxxx>]

Allow us to get the appropriate quota inode from any
mp & quota flags, not necessarily associated with a
particular dqp.  Needed for when we are searching for
the next active ID with quotas and we want to examine
the quota inode.
