Separate the CP ring polling logic in bnxt_poll_work() into 2 separate
functions __bnxt_poll_work() and __bnxt_poll_work_done(). Since the logic
is separated, we need to add tx_pkts and events fields to struct bnxt_napi
to keep track of the events to handle between the 2 functions. We also
add had_work_done field to struct bnxt_cp_ring_info to indicate whether
some work was performed on the CP ring.
This is needed to better support the 57500 chips. We need to poll up to
2 separate CP rings before we update or ARM the CP rings on the 57500 chips.
