[XFS] allow enabling CONFIG_XFS_DEBUG
Back when I first submitted XFS for mainline inclusion we made the decision that the debug code is far to extensive to be accidentally enabled by users in mainline. But then again it's often quite useful to track problems down and hacking the makefile all the time is rather annoying. Given all the debug options with even more overhead like lockdep or DEBUG_PAGE_ALLOC users (or rather developers) should know by now what they're doing.
