powerpc/ptdump: Fix DEBUG_WX since generic ptdump conversion

Browse Source 
commit 8d84fca4375e3c35dadc16b8c7eee6821b2a575c upstream.

In note_prot_wx() we bail out without reporting anything if
CONFIG_PPC_DEBUG_WX is disabled.

But CONFIG_PPC_DEBUG_WX was removed in the conversion to generic ptdump,
we now need to use CONFIG_DEBUG_WX instead.
