Previously vm_insert_pfn() returns err which has to
mapped into VM_FAULT_* type. The new function
vmf_insert_pfn() will replace this inefficiency by
returning VM_FAULT_* type.

As part of commit 2fae376c0a16db42eb438 in linux-next tree,
this conversion was missed. So
Return type of block_page_mkwrite() is converted to
vm_fault_t type. The caller of block_page_mkwrite
inside fs/nilfs2 nilfs_page_mkwrite converted accordingly.

Previously vm_insert_{pfn,mixed} returns err which driver
mapped into VM_FAULT_* type. The new function
vmf_insert_{pfn,mixed} will replace this inefficiency by
returning VM_FAULT_* type.
vmf_error() is the newly introduce inline function
in 4.17-rc6.
