Channel active/busy time are showing incorrect(less than previous or
sometimes zero) for successive survey dump command.

example:
Survey data from wlan0
	frequency:                      5180 MHz [in use]
	channel active time:            54995 ms
	channel busy time:              432 ms
	channel receive time:           0 ms
	channel transmit time:          59 ms
Survey data from wlan0
	frequency:                      5180 MHz [in use]
	channel active time:            32592 ms
	channel busy time:              254 ms
	channel receive time:           0 ms
	channel transmit time:          0 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.
