gfs2: Clean up function may_grant

Pass the first current glock holder into function may_grant and
deobfuscate the logic there.

While at it, switch from BUG_ON to GLOCK_BUG_ON in may_grant.  To make
that build cleanly, de-constify the may_grant arguments.

We're now using function find_first_holder in do_promote, so move the
function's definition above do_promote.
