Staging: brcm80211: fix usage of roundup in structures

Now that the roundup macro is sane, it can't be used in structure
definitions, or the build breaks..  For now, create a "broken_roundup()"
macro to get everything building again, but in the end, fixing these
structures to use a proper size value is the correct thing to do.
