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

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.

I have tested this on a QCA9980 device on a TP-Link Archer A7v5 with the
