Subject: rpmsg: glink: Initialize the "intent_req_comp" completion variable

From: Arun Kumar Neelakantam <aneela@codeaurora.org>


[ Upstream commit 2394facb17bcace4b3c19b50202177a5d8903b64 ]

The "intent_req_comp" variable is used without initialization which
results in NULL pointer dereference in qcom_glink_request_intent().

we need to initialize the completion variable before using it.
