scst: Move the code that decrements dev->not_pr_supporting_tgt_devs_num

Browse Source 
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.
