gnttab: correct pin status fixup for copy

Regardless of copy operations only setting GNTPIN_hst*, GNTPIN_dev*
also need to be taken into account when deciding whether to clear
_GTF_{read,writ}ing. At least for consistency with code elsewhere the
read part better doesn't use any mask at all.

This is XSA-230.
