Channel active/busy time are showing incorrect(less than previous or

example:
Survey data from wlan0

channel busy time: 432 ms
channel receive time: 0 ms
channel transmit time: 59 ms

This patch fix this issue by assigning 'wmi_bss_survey_req_type'
as 'WMI_BSS_SURVEY_REQ_TYPE_READ' which accumulate survey data in
FW and send survey data to driver upon the driver request. Wrap around
is taken care by FW.
hardware used : QCA9984
firmware ver : ver 10.4-3.5.3-00057
Have you tested this on other firmwares? I am pretty sure that at least
some of them, probably 10.2, will have issues.
Maybe you could make this change specific to certain firmware that
is known to work with the change?
Thanks,
Ben
