coresight-remote-etm: Adds missing lock to avoid race condition

We take a lock of drvdata->mutex and further wait on a lock
'drvdata->handle->handle_lock' in below path

remote_etm_disable => qmi_send_req_wait => qmi_encode_and_send_req

So, it is possible that while we wait on a handle lock in above mentioned
path The handle itself gets destroyed via below path

remote_etm_svc_exit => qmi_handle_destroy

and the handle is not valid anymore.

This patch adds lock drvdata->mutex at number of possible cases.
