Roger Pau Monné a2c5251281 xen/intr: improve PIRQ handling
Improve and cleanup the Xen PIRQ event channel code:

 - Remove the xi_shared field as it is unused.
 - Clean the "pending" bit in the EOI handler, this is more similar to how
   native interrupts are handled.
 - Don't mask edge triggered PIRQs, edge trigger interrupts cannot be
   masked.
 - Panic if PHYSDEVOP_eoi fails.
 - Remove the usage of the PHYSDEVOP_alloc_irq_vector hypercall because
   it's just a no-op in the Xen versions that are supported by FreeBSD Dom0.
