ice: manage interrupts during poll exit
The driver would occasionally miss that there were outstanding
descriptors to clean when exiting busy/napi poll. This issue has
been in the code since the introduction of the ice driver.
Attempt to "catch" any remaining work by triggering a software
interrupt when exiting napi poll or busy-poll. This will not
cause extra interrupts in the case of normal execution.
This issue was found when running sfnt-pingpong, with busy
poll enabled, and typically with larger I/O sizes like > 8192,
the program would occasionally report > 1 second maximums
to complete a ping pong.
