qcacld-3.0: Dont allocate reply skb without getting the request

Browse Source 
On LL_STATS debugfs request from the userspace driver is allocating
a reply vendor skb and trying to send the vendor command response
to userspace, resulting in kernel warning and rejecting the allocation.

Don't send the response to userspace if the command request is received 
for debugfs.
