[PATCH] perf/x86/intel/pt: drop pointless NULL assignment.

[PATCH] perf/x86/intel/pt: drop pointless NULL assignment.

[Paul Gortmaker]

Only a few lines below this removed line is this:

  attrs = kzalloc(size, GFP_KERNEL);

and since there is no code path where this could be avoided, the
NULL assignment is a pointless relic of history and can be removed.
