fs/namespace: add __user to open_tree and move_mount syscalls
Thw open_tree and move_mount syscalls take names from the
user, so add the __user to these to ensure the following
warnings from sparse are fixed:

fs/namespace.c:2392:35: expected char const [noderef] <asn:1> *name
fs/namespace.c:2392:35: got char const *filename
fs/namespace.c:3541:38: warning: incorrect type in argument 2 (different address spaces)
fs/namespace.c:3541:38: expected char const [noderef] <asn:1> *name
fs/namespace.c:3541:38: got char const *from_pathname
fs/namespace.c:3550:36: warning: incorrect type in argument 2 (different address spaces)
