  SVN rev 216812 on 2010-12-30 01:28:56Z by cperciva
  
  Add xenpic_dynirq_disable_intr and set it as the .pic_disable_intr method
  for xenpic_dynirq_template.  This fixes a panic when a virtual disk is
  removed, since that results in an interrupt channel being disabled and
  NULL isn't very good function for disabling interrupts.
  
  We should probably have a xenpic_pirq_disable_intr as well; I'm not adding
  that here because (a) I'm not sure what uses pirqs so I don't have a test
  case, and (b) the xenpic_pirq_enable_intr code is significantly more
  complex than the xenpic_dynirq_enable_intr code, so I'm not sure what
  should go into a xenpic_pirq_disable_intr routine.
