gianfar: Fix Rx BSY error handling
The Rx BSY error interrupt indicates that a frame was
received and discarded due to lack of buffers, so it's
a rx ring overflow condition and has nothing to do with
with bad rx packets. Use the right counter.
BSY conditions happen when the SoC is under performance
stress. Doing *more* work in stress situations by trying
to schedule NAPI is not a good idea as the stressed system
becomes still more stressed. The Rx interrupt is already
at work making sure the NAPI is scheduled.
So calling gfar_receive() here does not help. This issue
was present since day 1.
