Andrey Ryabinin 6d6f2833bf perf/x86: Fix undefined shift on 32-bit kernels
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.
