[PATCH 2/3] ublk_drv: uninitialized error code in ublk_ctrl_get_queue_affinity()

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

Initialize the "ret" variable so we don't return uninitialized data if
ublk_get_device_from_id() fails.

Fixes: 71f28f3136af ("ublk_drv: add io_uring based userspace block driver")
