HID: intel-ish-hid: ipc: Always schedule FW reset work on RESET_NOTIFY/ACK
Both ISH firmware and driver can actively send MNG_RESET_NOTIFY to initiate
an FW reset handshake. Upon receiving this, the peer should reply with
MNG_RESET_NOTIFY_ACK. Therefore, the driver should schedule the FW reset
handshake work function when receiving either MNG_RESET_NOTIFY or
MNG_RESET_NOTIFY_ACK.
Previously, driver only scheduled the work function on MNG_RESET_NOTIFY.
This patch ensures the work function is scheduled on both messages, but
only replies with MNG_RESET_NOTIFY_ACK when receiving MNG_RESET_NOTIFY.
