RDMA/uverbs: Use uverbs_attr_bundle to pass udata for write_ex
The core code needs to compute the udata so we may as well pass it in the uverbs_attr_bundle instead of on the stack. This converts the simple case of write_ex() which already has a core calculation. Also change the write() path to use the attrs for ib_uverbs_init_udata() instead of on the stack. This lets the write to write_ex compatibility path continue to follow the lead of the _ex path.
