perf/core: Change perf_mmap_fault() return type to 'vm_fault_t'

Use new return type 'vm_fault_t' for fault handlers.

For now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.

See the following commit:

  1c8f422059ae ("mm: change return type to vm_fault_t")
