x86: fix various issues with handling guest IRQs
- properly revoke IRQ access in map_domain_pirq() error path
- don't permit replacing an in use IRQ
- don't accept inputs in the GSI range for MAP_PIRQ_TYPE_MSI
- track IRQ access permission in host IRQ terms, not guest IRQ ones
(and with that, also disallow Dom0 access to IRQ0)
This is CVE-2013-1919 / XSA-46.
