decontaminate vfs operations from behavior details

All vfs ops now take struct xfs_mount pointers and the behaviour
related glue is split out into methods of it's own.


Signed-off-by: Christoph Hellwig <hch@lst.de>
Merge of xfs-linux-melb:xfs-kern:29504a by kenmcd.

  convert vfs ops to take xfs_mount pointers and split out
  the behaviour related glue.
