net: brcm80211: Deletion of unnecessary checks before two function calls
Author: Markus Elfring <elfring@users.sourceforge.net>
The functions brcmu_pkt_buf_free_skb() and release_firmware() test whether
their argument is NULL and then return immediately. Thus the test around
the call is not needed.
This issue was detected by using the Coccinelle software.
