RDMA/verbs: Store the write/write_ex uapi entry points in the uverbs_api
Bringing all uapi entry points into one place lets us deal with them
consistently. For instance the write, write_ex and ioctl paths can be
disabled when an API is not supported by the driver.
This will replace the uverbs_cmd_table static arrays.
