Commit fcdf31a7c162de0c93a2bee51df4688ab0a348f8 (xen/events/fifo:
Handle linked events when closing a port) did not handle closing a
port bound to a PIRQ because these are closed from shutdown_pirq()
which is called with interrupts disabled.
Defer the close to a work queue where we can safely spin waiting for
the LINKED bit to clear. For simplicity, the close is always deferred
even if it is not required (i.e., we're already in process context).
