Since nfs3_proc_create/nfs3_proc_mkdir/nfs3_proc_mknod these rpc ops are called
by nfs_create/nfs_mkdir/nfs_mkdir these inode ops, so they are all in control of
vfs.
nfs3_proc_setacls does nothing in the !CONFIG_NFS_V3_ACL case, so we put
posix_acl_create under CONFIG_NFS_V3_ACL and it also doesn't affect
sattr->ia_mode value because vfs has did umask strip.
