[ Upstream commit 63f6982075d890d7563e2469643f05a37d193f01 ]
Currently if an unsupported iftype is detected the error return path
does not free the cmd_skb leading to a resource leak. Fix this by
free'ing cmd_skb.
Addresses-Coverity: ("Resource leak")
Fixes: 805b28c05c8e ("qtnfmac: prepare for AP_VLAN interface type support")
