soc: qcom: glink_pkt: fix number of intent queued

glink_pkt driver has no limit on number of intents auto queued for rx.
Intent are auto queued when remote side request for intent without checking
how many packets are pending to be read by client.

A max limit check is added to avoid memory exhaustion case with indefinite
intent queueing.
