Thread-topic:	[PATCH] Add check for mapping MSI pirqs

Hi, Keir,

This patch adds a missing check for pirq values after mapping MSI pirqs.

Normally, if mapping pirq succeeds, xen will return pirq value mapped.
However, if "msi_irq_enable = 1" is not specified, this hypercall still
succeeds, but pirq value is not valid.

Best Regards
Haitao Shan
