Jan Beulich 545c837d67 Xen/gnttab: handle p2m update errors on a per-slot basis
commit 8310b77b48c5558c140e7a57a702e7819e62f04e upstream.

Bailing immediately from set_foreign_p2m_mapping() upon a p2m updating
error leaves the full batch in an ambiguous state as far as the caller
is concerned. Instead flags respective slots as bad, unmapping what
was mapped there right away.

HYPERVISOR_grant_table_op()'s return value and the individual unmap
slots' status fields get used only for a one-time - there's not much we
can do in case of a failure.

Note that there's no GNTST_enomem or alike, so GNTST_general_error gets
used.

The map ops' handle fields get overwritten just to be on the safe side.

This is part of XSA-367.
