Sebastian Andrzej Siewior fc37191272 userns: use refcount_t for reference counting instead atomic_t ...

refcount_t type and corresponding API should be used instead of atomic_t
wh en the variable is used as a reference counter.  This avoids accidental
refcounter overflows that might lead to use-after-free situations.
