soc: qcom: glink_smd_xprt: Cleanup current intent reference at SSR 



If a packet is partially processed, a reference to the related intent is
kept in the channel for completing the packet processing at a later time.
This reference is not cleaned up during SSR, which may cause the stale
reference to be incorrectly used after SSR, which could result in a crash.

Clean up the reference in SSR when it becomes invalid to prevent incorrect
behavior post-SSR.
