RDMA/uverbs: Simplify UVERBS_OBJECT and _TREE family of macros
Instead of the large set of indirecting macros, define the few needed
macros to directly instantiate the struct uverbs_oject_tree_def and
associated objects list.
This is small amount of code duplication but the readability is far
better.
