bnxt_en: Improve bnxt_ulp_stop()/bnxt_ulp_start() call sequence.
We call bnxt_ulp_stop() to notify the RDMA driver that some error or
imminent reset is about to happen. After that we always call
some variants of bnxt_close().
In the next patch, we will integrate the recently added error
recovery with the RDMA driver. In response to ulp_stop, the
RDMA driver may free MSIX vectors and that will also trigger
bnxt_close(). To avoid bnxt_close() from being called twice,
we set a new flag after ulp_stop is called. If the RDMA driver
frees MSIX vectors while the new flag is set, we will not call
bnxt_close(), knowing that it will happen in due course.
With this change, we must make sure that the bnxt_close() call
after ulp_stop will reset IRQ. Modify bnxt_reset_task()
accordingly if we call ulp_stop.
