qcacld-3.0: Reconfig OBSS periodicity upon NDP create/delete

When STA is connected to an 11ax AP, driver issues a scan request(OBSS)
to firmware with certain periodicity(it's 120 seconds currently).
Firmware shall do a scan for every 120 seconds irrespective of the
device activity. This causes data glitches throughout the scan duration
when data is going on a concurrent interface.
It's observed that the OBSS scan interrupts NDP data traffic from NDP
applications and causes glitches in file sharing/music sharing use cases.

Configure the OBSS scan periodicity with a larger value(1200 seconds) to
mitigate the glitches when first NDP forms. Reconfigure the original
scan duration(120 seconds) once all NDPs tear down.
