David Arcari ba893caead tools/power turbostat: Allow execution to continue after perf_l2_init() failure ...

Currently, if perf_l2_init() fails turbostat exits after issuing the
following error (which was encountered on AlderLake):

turbostat: perf_l2_init(cpu0, 0x0, 0xff24) REFS: Invalid argument

This occurs because perf_l2_init() calls err(). However, the code has been
written in such a manner that it is able to perform cleanup and continue.
Therefore, this issue can be addressed by changing the appropriate calls
to err() to warnx().

Additionally, correct the PMU type arguments passed to the warning strings
in the ecore and lcore blocks so the logs accurately reflect the failing
counter type.
