perf/x86: Fix incorrect PEBS_REGS
PEBS_REGS used as mask for the supported registers for large PEBS.
However, the mask cannot filter the sample_regs_user/sample_regs_intr
correctly.
(1ULL << PERF_REG_X86_*) should be used to replace PERF_REG_X86_*, which
is only the index.
Rename PEBS_REGS to PEBS_GP_REGS, because the mask is only for general
purpose registers.

[ Renamed it to PEBS_GP_REGS - as 'GPRS' is used elsewhere ;-) ]
