Reduce struct isc__nm_uvreq size from 1560 to 560 bytes

The uv_req union member of struct isc__nm_uvreq contained libuv request
types that we don't use.  Turns out that uv_getnameinfo_t is 1000 bytes
big and unnecessarily enlarged the whole structure.  Remove all the
unused members from the uv_req union.
