When firmware indicates that driver needs to invoke firmware reset
which is common for both error recovery and live firmware reset path,
driver needs a different time to wait before polling for firmware
readiness.

Modify the wait time to fw_reset_min_dsecs, which is initialised to
correct timeout for error recovery and firmware reset.
