Refactors how grants are claimed/released/revoked by moving that code

But should this be generic?  Is it useful to other frontends?  And some
of the line splitting looks a bit odd.

It looks like scsifront (lines 384-389, 418-423), blkfront (lines 250-257)
and netfront both grant their buffers in the same way, so perhaps these two
helpers could be reused.
