msm: kgsl: Print always on counters if HFI timed out

This patch adds some instrumentation to dump the always on
counters in case the polling routine timed out waiting for a response
from GMU after we send the HFI command. There are some cases
where we suspect that the polling logic may be prematurely timing
out. This patch should help throw more light into such cases.
