[PATCH 61/83] perf report: Ignore kptr_restrict when not sampling the kernel

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

If none of the evsels has attr.exclude_kernel set to zero, no kernel
samples, so no point in warning the user about problems in processing
kernel samples, as there will be none.
