Rosalloc should print unreachable page map type

When rosalloc receives unexpected page map type, it is not
printed in error message because it has 'byte' type. When printed
to LOG(FATAL), it is interpreted as symbol (usually unprintable).
This patch allows to see unexpected page map types as integers.
