[PATCH] IB/ipoib: rename global symbols

Make IPoIB data_debug_level module parameter static to the single file
where it is used.  Also Rename IPoIB module parameter variable from
"debug_level" to "ipoib_debug_level".  This avoids possible name
clashes if IPoIB is built into the kernel.  We use module_param_named
so that the user-visible parameter names remain the same.
