Alexander Motin 2f03a95fd2 Fix few issues in ioat(4) driver. ... - Do not explicitly count active descriptors. It allows hardware reset to happen while device is still referenced, plus simplifies locking. - Do not stop/start callout each time the queue becomes empty. Let it run to completion and rearm if needed, that is much cheaper then to touch it every time, plus also simplifies locking. - Decouple submit and cleanup locks, making driver reentrant. - Avoid memory mapped status register read on every interrupt. - Improve locking during device attach/detach. - Remove some no longer used variables.
