qcacmn: extract max number of NAN pairing sessions

Browse Source 
Currently, there is no provision to identify that the driver supports
NAN pairing protocol. So, new kernel and new firmware will start
exchanging PASN frames without realization that old driver is loaded
and thus, frames will be drops in driver.

So, to fix this issue, firmware introduces new parameter in nan
capabilities to indicate host about pairing capability. Host driver
extracts the TLV to get nan capabilities and cache the max num of
pairing session.
