[PATCH v2 08/20] arm: perf/core: remove unnecessary checks for exclusion

[Andrew Murray]

For drivers that do not support context exclusion we do not
advertise the PERF_PMU_CAP_EXCLUDE capability. This ensures that
perf will prevent us from handling events where any exclusion
flags are set. Let's remove the now unnecessary check for
exclusion flags.
