qcacld-3.0: Don't reject SR command if threshold not provided

As per current implementation, SR(Spatial Reuse) commands are
rejected if STA is not connected or connected to AP that doesn't
support SR which causes issue because SR Enable/Disable command
shouldn't reject if STA is not connected instead of rejection
same configuration should be applied when SR AP connects to STA.

Fix is to not to reject SR command if PD threshold is not provided
along with enable command, so that enable command can be accepted and
applied when AP that supports SR connects to station.
