perf/x86/intel/pt: Fix address filter config for 32-bit kernel
[ Upstream commit e5524bf1047eb3b3f3f33b5f59897ba67b3ade87 ]
Change from shifting 'unsigned long' to 'u64' to prevent the config bits
being lost on a 32-bit kernel.
Fixes: eadf48cab4b6b0 ("perf/x86/intel/pt: Add support for address range filtering in PT")
