Andrew Cooper 07e8f88568 x86/apic: Drop apic::delivery_mode 
This field is set to APIC_DELIVERY_MODE_FIXED in all cases, and is read
exactly once.  Fold the constant in uv_program_mmr() and drop the field.

Searching for the origin of the stale HyperV comment reveals commit
a31e58e129 ("x86/apic: Switch all APICs to Fixed delivery mode") which
notes:

  As a consequence of this change, the apic::irq_delivery_mode field is
  now pointless, but this needs to be cleaned up in a separate patch.

6 years is long enough for this technical debt to have survived.
