Vineet Gupta dc89e75a94 tools/perf: Handle -EOPNOTSUPP for sampling events 
This allows (with a previous change to the perf error return ABI) for
calling out in userspace the exact reason for perf record failing
when PMU doesn't support overflow interrupts.

Note that this needs to be put ahead of existing precise_ip check as
that gets hit otherwise for the sampling fail case as well.
