RDMA/uverbs: Use cdev_device_add() instead of cdev_add()
Instead of doing two step process to add char device and create underlying
device, use cdev_device_add() which does both.
Currently a kobject per uverbs_device is created to keep reference to its
holding ib_uverbs_device in addition to its underlying device 'dev'.
Instead just use uverbs_device->dev to keep a reference to.
With this change there is single reference tracker for ib_uverbs_device
structure.
This allows for subsequent patch to registers group attribute as well
using single API cdev_device_add().
