soc: qcom: glink: Initialize local state while fetching ctx

Initialization of channel's local state is not done at the time of
fetching context from list of channels. This leads to race condition
if remote close happens during this time. Remote close will check if
local state is not open then delete channel from list. This leads to
use after free scenerio.

Initialize local state at the time of fetching channel context from
list of channels.
