IB/umad: Convert *cdev to cdev in struct ib_umad_port
Instead of storing pointers to cdev and sm_cdev, embed the full
structures instead.
This change allows us to use the container_of() macro in ib_umad_open()
and ib_umad_sm_open() in a future patch.
This change increases the size of struct ib_umad_port to 320 bytes
from 128.
