qcacmn: Disable CP Stats for BE emulation

Disable CP Stats for Beryllium emulation environment. These stats are
invoked heavily by userspace and need to be retrieved from the FW.The
userpace is holding the rtnl_lock while invoking these stats. This
prevents any additional commands to be sent while a stats command is
pending. Since in emulation environment, the turnaround time is quite
high, no iwpriv/ifconfig/iw command can be sent while the CP stats are
pending, making the driver in accessible from command line.

Hence, disable CP stats by simply returning 0 to the caller in emulation
environment.
