KVM: Drop unused @may_block param from gfn_to_pfn_cache_invalidate_start()

Browse Source 
Remove gfn_to_pfn_cache_invalidate_start()'s unused @may_block parameter,
which was leftover from KVM's abandoned (for now) attempt to support guest
usage of gfn_to_pfn caches.

Fixes: a4bff3df51 ("KVM: pfncache: remove KVM_GUEST_USES_PFN usage")
