1/ remove 'start' and 'end' args from nfs_file_fsync_commit().
They aren't used.
2/ Make nfs_context_set_write_error() a "static inline" in internal.h
so we can...
3/ Use nfs_context_set_write_error() instead of mapping_set_error()
if nfs_pageio_add_request() fails before sending any request.
NFS generally keeps errors in the open_context, not the mapping,
so this is more consistent.
4/ If filemap_write_and_write_range() reports any error, still
check ctx->error. The value in ctx->error is likely to be
more useful. As part of this, NFS_CONTEXT_ERROR_WRITE is
cleared slightly earlier, before nfs_file_fsync_commit() is called,
rather than at the start of that function.
