Subject: [PATCH] powerpc/ptdump: fix conversion to GENERIC_PTDUMP

Commit e084728393a5 ("powerpc/ptdump: Convert powerpc to GENERIC_PTDUMP")
replaces the use of the powerpc-specific config PPC_DEBUG_WX by the
generic DEBUG_WX. The commit misses the use of PPC_DEBUG_WX in the
function note_prot_wx().

Replace this last occurrence of PPC_DEBUG_WX to complete the conversion.

This issue is identified with the script ./scripts/checkkconfigsymbols.py.
