net: enetc: fix incorrect mailbox message status returned to VFs
There are two cases where VFs receive an incorrect success status from
the PF mailbox message handler, misleading them into believing their
requests have been fulfilled:
In enetc_msg_handle_rxmsg(), *status is pre-initialized to
ENETC_MSG_CMD_STATUS_OK. When an unsupported command type is received,
the default case only logs an error without updating *status, so it
remains as ENETC_MSG_CMD_STATUS_OK.
In enetc_msg_pf_set_vf_primary_mac_addr(), when the PF has already
assigned a MAC address for the VF (ENETC_VF_FLAG_PF_SET_MAC is set),
the function rejects the request but returns ENETC_MSG_CMD_STATUS_OK
instead of ENETC_MSG_CMD_STATUS_FAIL.
Therefore, correct the status value for the two cases mentioned above.
