soc: qcom: glink_pkt: Handle GLINK_LOCAL_DISCONNECTED event

The client close() call is returned immediately without handling
the GLINK_LOCAL_DISCONNECTED event allows the client to re-open
the device again while glink core processing the previous close ACK.

To avoid open/close race condition block the close() function call
until the GLINK_LOCAL_DISCONNECTED event received from the core.
