Revert "mm/secretmem: use refcount_t instead of atomic_t"
This reverts commit 110860541f443f950c1274f217a1a3e298670a33.
Converting the "secretmem_users" counter to a refcount is incorrect,
because a refcount is special in zero and can't just be incremented (but
a count of users is not, and "no users" is actually perfectly valid and
not a sign of a free'd resource).
