Thomas Gleixner 1638b8f096 lib/vdso: Make clock_getres() POSIX compliant again ... A recent commit removed the NULL pointer check from the clock_getres() implementation causing a test case to fault. POSIX requires an explicit NULL pointer check for clock_getres() aside of the validity check of the clock_id argument for obscure reasons. Add it back for both 32bit and 64bit. Note, this is only a partial revert of the offending commit which does not bring back the broken fallback invocation in the the 32bit compat implementations of clock_getres() and clock_gettime().
