perf/x86/intel/pt: Fix address filter config for 32-bit kernel

Browse Source 
[ Upstream commit e5524bf104 ]

Change from shifting 'unsigned long' to 'u64' to prevent the config bits
being lost on a 32-bit kernel.

Fixes: eadf48cab4 ("perf/x86/intel/pt: Add support for address range filtering in PT")
