[Impact]
A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in 
drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux 
Kernel. This issue could occur when assoc_info->req_len data is bigger than 
the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading to a denial of 
service. 

[Backport]
It is a clean cherry pick.

[Test]
Compile and smoke tested via modprobe and rmmod the brmcfmac module.

[Potential Regression]
Expecting low potential of regression as the fix only adds an additionaly layer
of sanity check.
