mm/hmm: convert to use vm_fault_t
Convert to use vm_fault_t type as return type for fault handler.
kbuild reported warning during testing of
*mm-create-the-new-vm_fault_t-type.patch* available in below link -
https://patchwork.kernel.org/patch/10752741/
kernel/memremap.c:46:34: warning: incorrect type in return expression
(different base types)
kernel/memremap.c:46:34: expected restricted vm_fault_t
kernel/memremap.c:46:34: got int
This patch has fixed the warnings and also hmm_devmem_fault() is
converted to return vm_fault_t to avoid further warnings.
