powerpc/mm: Don't log user reads to 0xffffffff
Running vdsotest leaves many times the following log:
[ 79.629901] vdsotest[396]: User access of kernel address (ffffffff) - exploit attempt? (uid: 0)
A pointer set to (-1) is likely a programming error similar to
a NULL pointer and is not worth logging as an exploit attempt.
Don't log user accesses to 0xffffffff.
