[PATCH] perf/x86/intel/pt: Fix a refactoring glitch

[Alexander Shishkin]

Commit 066450be41 ("perf/x86/intel/pt: Clean up the control flow in
pt_pmu_hw_init()") changed attribute initialization so that only the
first attribute gets initialized using sysfs_attr_init(), which upsets
lockdep.

This patch fixes the glitch so that all allocated attributes are properly
initialized thus fixing the lockdep warning reported by Tvrtko and Imre.
