qcacld-3.0: Don't allow SR operation in disconnected state

Currently, SR enable can be set even if sta is not connected
to AP due to which success is returned to userspace but command
is not sent to FW.
Fix is to not to entertain any SR operation if station is not
connected or connected AP is not supporting SR.
