rpmsg: glink: Cancel pending intent requests at removal
During removal of the glink edge interrupts are disabled and no more
incoming messages are being serviced. In addition to the remote endpoint
being defunct that means that any outstanding requests for intents will
not be serviced, and qcom_glink_request_intent() will blindly wait for
up to 10 seconds.
Mark the intent request as not granted and complete the intent request
completion to fail the waiting client immediately.
Once the current intent request is failed, any potential clients waiting
for the intent request mutex will not enter the same wait, as the
qcom_glink_tx() call will fail fast.
