Qiujun Huang 1165dd73e8 staging: wlan-ng: fix use-after-free Read in hfa384x_usbin_callback
We can't handle the case length > WLAN_DATA_MAXLEN.
Because the size of rxfrm->data is WLAN_DATA_MAXLEN(2312), and we can't
read more than that.

TODO:
	- checkpatch.pl cleanups
	- sparse warnings
	- move to use the in-kernel wireless stack

Please send any patches or complaints about this driver to Greg
Kroah-Hartman <greg@kroah.com> and don't bother the upstream wireless
kernel developers about it, they want nothing to do with it.
