target/iscsi: Inline iscsit_allocate_se_cmd and *_for_tmr
Trying to move a bunch of stuff around so iscsi can use target_submit_cmd someday, and so stuff needs to be in that function directly instead of hidden, so it can be reordered etc. Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
