perf/x86/intel/pt: Relax address filter validation
The requirement for 64-bit address filters is that they are canonical
addresses. In other respects any address range is allowed which would
include user space addresses.
That can be useful for tracing virtual machine guests because address
filtering can be used to advantage in place of current privilege level
(CPL) filtering.
