ath10k: fix scan abort when duration is set for hw scan
When request scan with duration 120ms on channel 1, it failed with
scan abort easily. Because scan_timeout is set to 130ms for the scan
in ath10k_hw_scan(), and timed out before scan complete, so lead
scan abort.

This is to increase the scan_timeout with 200ms for this situation,
then scan will not timed out for this situation.
