[PATCH 02/13] perf/core: Extend perf_sample_regs_intr() to include perf_arch_regs update

Extend perf_sample_regs_intr() to support the updates needed for perf_arch_reg structure and perf_arch_regs_mask. Also add code to init the arch_regs_mask to zero incase of regs_user in perf_sample_regs_user(). Ideally this should be done in perf_sample_data_init, but due to commit 2565711fb7d7
