gma skl: Prevent race by late timeout check

We initialize the timeout variable before the first event on the other
side (i.e. us sending a request to PCODE). With very slow debug output
sending the request itself might take longer than the timeout period.

Reorder the code to check the timeout condition only after the first
try and thereby make sure that we always try at least twice. Also issue
a debug message in case we timed out.
