irqfd_wakeup() gets EPOLLHUP, when it is called by
eventfd_release() by way of wake_up_poll(&ctx->wqh, EPOLLHUP), which
gets called under spin_lock_irqsave(). We can't use a mutex here as it
will lead to a deadlock.
Fix it by switching over to a spin lock.

Increment the counter before checking for number of rules, otherwise
when there's no XE_RTP_MATCH_OR an out-of-bounds access is done, as
