Christophe Leroy e963b7a28b powerpc/vdso32: Fallback on getres syscall when clock is unknown 
There are other clocks than the standard ones, for instance
per process clocks. Therefore, being above the last standard clock
doesn't mean it is a bad clock. So, fallback to syscall instead
of returning -EINVAL inconditionaly.

Fixes: e33ffc956b ("powerpc/vdso32: implement clock_getres entirely")
