cfg80211: mark expected switch fall-throughs 

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

This patch fixes the following warnings:

net/wireless/wext-compat.c:1327:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
net/wireless/wext-compat.c:1341:6: warning: this statement may fall through [-Wimplicit-fallthrough=]

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enabling
-Wimplicit-fallthrough
