target: Convert se_device statistics to atomic_long_t
This patch converts the handful of se_device statistics to type
atomic_long_t, instead of using se_device->stats_lock when
incrementing these values.
More importantly, go ahead and drop the spinlock usage within
transport_lookup_cmd_lun() fast-path code.
