When a reset type that is not supported by the driver is input, a reset
pending flag bit of the HNAE3_NONE_RESET type is generated in
reset_pending. The driver does not have a mechanism to clear this type
of error. As a result, the driver considers that the reset is not
complete. This patch provides a mechanism to clear the
HNAE3_NONE_RESET flag and the parameter of
hnae3_ae_ops.set_default_reset_request is verified.
The error message:
hns3 0000:39:01.0: cmd failed -16
hns3 0000:39:01.0: hclge device re-init failed, VF is disabled!
