Subject: [PATCH net 5/5] bnxt_en: Fix warning in bnxt_dl_reload_down()

From: Shantiprasad Shettar <shantiprasad.shettar@...adcom.com>

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.

Fixes: 228ea8c187d8 ("bnxt_en: implement devlink dev reload driver_reinit")
