[PATCH] ath10k: Change the fw stats access mask

[Yanbo Li]

This fix the regerssion introduced after "ath10k_wmi_requests_stats()
call to use more stat bits", both the 10.2.X FW and community FW 10.1.X
will return time out when access the fw_stats with the STAT_VDEV and
STAT_PDEV. Add the condition to use different fw_stats mask for different
FW versions.
