perf/x86/intel/pt: Fix a refactoring bug
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.
