[PATCH v2 09/16] infiniband: utilize the new cdev_set_parent function

[Logan Gunthorpe <logang-OTvnGxWRz7hWk0Htik3J/w@public.gmane.org>]

This replaces the suspect looking cdev.kobj.parent lines with the
equivalent cdev_set_parent function. This is a straightforward change
that's largely cosmetic but it does push the kobj.parent ownership
into char_dev.c where it belongs.
