remove global stats lock from item allocation

This doesn't reduce mutex contention much, if at all, for the global stats
lock, but it does remove a handful of instructions from the alloc hot path,
which is always worth doing.

Previous commits possibly added a handful of instructions for the loop and for
the bucket readlock trylock, but this is still faster than .14 for writes
overall.
