eventpoll: rename ep_refcount_dec_and_test() to ep_put()

ep_refcount_dec_and_test() mirrors refcount_dec_and_test() verbatim,
which reads fine at a call site like

  if (ep_refcount_dec_and_test(ep))
      ep_free(ep);

but awkward at

  WARN_ON_ONCE(ep_refcount_dec_and_test(ep));

and does not pair cleanly with ep_get(). Rename to the idiomatic
ep_put() and reword the kerneldoc to spell out the return-value
contract (caller is responsible for ep_free() iff the return is
true). Leave ep_put() as a bool-returning wrapper -- we cannot fold
ep_free() into it because ep_remove() calls it under ep->mtx and the
mutex would still be held when ep_free()'s mutex_destroy() ran (see
commit 8c2e52ebbe88 "eventpoll: don't decrement ep refcount while
still holding the ep mutex").

No functional change.
