wimax: fix '#ifndef CONFIG_BUG' layout to avoid warning
Reported by Randy Dunlap:
> Also, this warning needs to be fixed:

> linux-next-20090106/net/wimax/id-table.c:133: warning: ISO C90
> forbids mixed declarations and code
Move the return on #defined(CONFIG_BUG) below the variable
declarations so it doesn't violate ISO C90.
On wimax_id_table_release() we want to do a debug check if CONFIG_BUG
is enabled. However, we also want the debug code to be always compiled
to ensure there is no bitrot. It will be optimized out by the compiler
when CONFIG_BUG is disabled.
Added a note to the function header stating this.
