Subject: [PATCH] mm: zswap: use ATOMIC_LONG_INIT to initialize zswap_stored_pages

This is currently the only atomic_long_t variable initialized by
ATOMIC_INIT macro found in the kernel by using
`grep -r atomic_long_t | grep ATOMIC_INIT`

This was introduced in 6e1fa555ec77, in which we modified
the type of zswap_stored_pages to atomic_long_t,
but didn't change the initialization.

Fixes: 6e1fa555ec77 ("mm: zswap: modify zswap_stored_pages to be atomic_long_t")
