brcm80211: fmac: fix a couple checking after dereference bugs
There were two dereferencing before checking for NULL static checker complaints in this new file. The list cursor is never NULL so that check can be removed. I moved the other dereference after the check. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Arend van Spriel <arend@broadcom.com> Signed-off-by: John W.
