[PATCH v2 2/2] net/tap: fix use after free on interrupt handle

[David Marchand <david.marchand@redhat.com>]

This driver was not unregistering its interrupt callbacks when closing
the port, which now means use after free after the interrupt handle
is not duplicated anymore by the interrupt thread.

Fixes: c663018eb7f3 ("interrupts: do not duplicate interrupt handles")
