Subject: [PATCH v12 18/25] x86/resctrl: Fix types in resctrl_arch_mon_ctx_{alloc,free}() stubs

resctrl_arch_mon_ctx_alloc() and resctrl_arch_mon_ctx_free() take an enum
resctrl_event_id that is already defined in resctrl_types.h to be
accessible to asm/resctrl.h.

The x86 stubs take an int. Fix that.
