Smatch is warning about a dereference before we check for NULL.
This patch moves the dereference to after the NULL check.

In commit 1ca1a92cc6 "Staging: wlan-ng: memsetting the wrong amount of
data" I changed the code so we didn't memset() past the end of the
msg1.bssid.data[] array. Walter Harms noticed that it was weird that
we were setting the len to 6 when there were 7 elements in the array.
Pavel Roskin pointed out that the intent of the code was actually to
memset() msg1.bssid.data.data[] which is a 6 character array.

p80211item_pstr6_t is the size of "msg1.bssid" (16 bytes) but
msg1.bssid.data is type p80211pstr6_t and it is smaller (7 bytes). We
had just set that memory to zeroes earlier and now we're writing over it
with 0xff because we're writing past the end of the struct.
I don't know if this actually causes a problem. It may be that we
initialize the extra 0xff bytes correctly later. But the current code
is obviously wrong and we should fix it.

This converts the drivers in drivers/staging/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.
Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

cfg80211 scan code adds separate BSS entries if the same BSS shows up
on multiple channels. However, sme implementation does not use the
frequency when fetching the BSS entry. Fix this by adding channel
information to cfg80211_roamed() and include it in cfg80211_get_bss()
calls.
Please note that drivers using cfg80211_roamed() need to be modified to
fully implement this fix. This commit includes only minimal changes to
avoid compilation issues; it maintains the old (broken) behavior for
most drivers. ath6kl was the only one that I could test, so I updated
it to provide the operating frequency in the roamed event.
