qcacmn: disable EXT grp irqs and drain TXRX during suspend

Browse Source 
Any update to the SRNG TP/HP when the device is in low power
state would result in system errors. It is recommended to disable
EXT grp irqs and drain TXRX before sending power save enter command
to the FW. This will ensure that no interrupts are received while
in power save mode and as a result there wont be any HP/TP updates.
