====================
net: ipa: NAPI poll updates

While reviewing the IPA NAPI polling code in detail I found two
problems.  This series fixes those, and implements a few other
improvements to this part of the code.

The first two patches are minor bug fixes that avoid extra passes
through the poll function.  The third simplifies code inside the
polling loop a bit.

The last two update how interrupts are disabled; previously it was
possible for another I/O completion condition to be recorded before
NAPI got scheduled.
