Move the ublk_ctrl_*() helpers and ublk_setup_ring() out of kublk.c,
so a small test program can send control commands without copying
them. kublk still links every *.c file, ctrl.c included.
ublk_ctrl_deinit() now also exits the control ring, and ublk_ctrl_init()
checks the allocation and closes /dev/ublk-control when the ring setup
fails. kublk calls them only around its own lifetime, but a test which
opens a control handle per thread must not leak.
No functional change for kublk.
