staging/rdma/hfi1: Clear the QSFP reset that is asserted on FLR

not deassert it after. This patch allows the external QSFP cable to exit

There are some race conditions when check/use cfs_fail_val.
For example: when inject failure stub for LFSCK test as following:

764   if (OBD_FAIL_CHECK(OBD_FAIL_LFSCK_DELAY2) &&
765       cfs_fail_val > 0) {
766           struct l_wait_info lwi;
767
768           lwi = LWI_TIMEOUT(cfs_time_seconds(cfs_fail_val),
769                             NULL, NULL);
770           l_wait_event(thread->t_ctl_waitq,
771                        !thread_is_running(thread),
772                        &lwi);
773
774           if (unlikely(!thread_is_running(thread))) {
775                   CDEBUG(D_LFSCK, "%s: scan dir exit for engine "
776                          "stop, parent "DFID", cookie "LPX64"n",
777                          lfsck_lfsck2name(lfsck),
778                          PFID(lfsck_dto2fid(dir)),
779                          lfsck->li_cookie_dir);
780                   RETURN(0);
781           }
782   }

The "cfs_fail_val" may be changed as zero by others after the check
at the line 765 but before using it at the line 768. Then the LFSCK
engine will fall into "wait" until someone run "lfsck_stop".
