Merge branch 'bnxt_en-fixes'

Michael Chan says:

====================
bnxt_en: 2 bug fixes.

The first patch prevents possible driver crash if we get a bad RX index
from the hardware.  The second patch resets the device when the hardware
reports buffer error to recover from the error.

Please queue these for -stable also.  Thanks.
