soc: qcom: msm_glink_pkt: remove the wakeup source during device close

Browse source 
Client closing the device immediately after receiving data leaves
the packet arrival wakeup source in active state and block the system
infinitely from entering into suspend state.

Check the state of wakeup source during close operation and release
if it is active.
