net: hns3: fixed reset failure issues caused by the incorrect reset type

Browse source 
[ Upstream commit 5a4b584c67 ]

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!
hns3 0000:39:01.0: failed to reset VF stack
hns3 0000:39:01.0: failed to reset VF(4)
hns3 0000:39:01.0: prepare reset(2) wait done
hns3 0000:39:01.0 eth4: already uninitialized

Use the crash tool to view struct hclgevf_dev:
struct hclgevf_dev {
...
	default_reset_request = 0x20,
	reset_level = HNAE3_NONE_RESET,
	reset_pending = 0x100,
	reset_type = HNAE3_NONE_RESET,
...
};
