Fixing a memory leak in xpt_release_device(), which can be quickly
(depends on how many memory you have) observed through "tar -tvf /dev/sa0."
Without this patch, RELENG_5 and HEAD panics with something like:
kmem_malloc(4096): kmem_map too small: 42258432 total allocated
RELENG_4 doesn't panic but spews following errors:
camq_init: - cannot malloc array!
