[PATCH] perf/x86: fix undefined shift on 32-bit kernels

[Andrey Ryabinin]

Jim reported:
        UBSAN: Undefined behaviour in arch/x86/events/intel/core.c:3708:12
        shift exponent 35 is too large for 32-bit type 'long unsigned int'

The use of 'unsigned long' type obviously is not correct here, make it
'unsigned long long' instead.

Fixes: 2c33645d366d ("perf/x86: Honor the architectural performance monitoring 
version")
