bnxt_en: Fix warning in bnxt_dl_reload_down()

The existing code calls bnxt_cancel_reservations() after
bnxt_hwrm_func_drv_unrgtr() in bnxt_dl_reload_down().
bnxt_cancel_reservations() calls the FW and it will always fail since
the driver has already unregistered, triggering this warning:

bnxt_en 0000:0a:00.0 ens2np0: resc_qcaps failed

Fix it by calling bnxt_clear_reservations() which will skip the
unnecessary FW call since we have unregistered.
