So this is similar work to what has been posted here [0] for ath12k.
When we use the pattern 'return ath11k_wmi_cmd_send(...)' without
explicitly checking the return value we fail to free the allocated skb.
This has been split into 2 patches per Jeff's guidance to hopefully
ease the backporting process.
