perf/x86/intel: Correct large PEBS flag check

current large PEBS flag check only checks if sample_regs_user contains
unsupported GPRs but doesn't check if sample_regs_intr contains
unsupported GPRs.

Of course, currently PEBS HW supports to sample all perf supported GPRs,
the missed check doesn't cause real issue. But it won't be true any more
after the subsequent patches support to sample SSP register. SSP
sampling is not supported by adaptive PEBS HW and it would be supported
until arch-PEBS HW. So correct this issue.
