Subject: [PATCH] qtnfmac: fix resource leaks on unsupported iftype error return path
Git-commit: 63f6982075d890d7563e2469643f05a37d193f01
Patch-mainline: v5.10-rc1
References: git-fixes

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")
