ublk: improve getting & putting ublk device
Firstly convert get_device() and put_device() into ublk_get_device()
and ublk_put_device().
Secondly annotate ublk_get_device() & ublk_put_device() as noinline
for trace, especially it is often to trigger device deletion hang
when incorrect order is used on ublkc mmap, ublkc close,
io_uring_sqe_unregister_file, ublkb close.
