[PATCH 2/2] perf/x86/regs: Check reserved bits

From: Kan Liang The perf fuzzer triggers a warning which map to: if (WARN_ON_ONCE(idx >= ARRAY_SIZE(pt_regs_offset))) return 0; The bits between XMM registers and generic registers are reserved. But perf_reg_validate() doesn't check these bits. Add REG_RESERVED for
