7426031e91 scst: Free removed LUNs asynchronously 
Since scst_free_tgt_dev() is called as soon as the tgt_dev refcount
drops to zero and since scst_del_tgt_dev() decrements that reference
count, remove all scst_free_tgt_dev() calls that follow a
scst_del_tgt_dev() call. Set nr_deleted_tgt_devs in scst_acg_add_lun()
to -1 to avoid that all scst_del_tgt_dev() calls try to free the
associated acg_dev.

8064fdcf34 scst: Move the code that decrements dev->not_pr_supporting_tgt_devs_num 
A later patch will introduce a delay between deleting and freeing a tgt_dev.
Move the code that decrements dev->not_pr_supporting_tgt_devs_num from the
function that frees a tgt_dev into the function that deletes a tgt_dev such
that the decrement code does not get delayed.
