From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently the null check on a newly allocated skb is missing and
this can lead to a null pointer dereference is the allocation fails.
Fix this by adding a null check and returning -ENOMEM.
Addresses-Coverity: ("Dereference null return")
Fixes: 43ed15e1ee01 ("ath11k: put hw to DBS using WMI_PDEV_SET_HW_MODE_CMDID")
