If we are doing a complete reset with irq_re_init set to true in
bnxt_close_nic(), all the ring structures will be freed.  New
structures will be allocated in bnxt_open_nic().  The current code
increments rx_resets counter in bnxt_enable_napi() if bnapi->in_reset
is true.  In a complete reset, bnapi->in_reset will never be true
since the structure is just allocated.

Increment the rx_resets counter in bnxt_disable_napi() instead.  This
will allow us to save all the ring error counters including the
rx_resets counters in the next patch.
