freedreno/ir3: drop shader->num_ubos
The only difference between this and `const_state->num_ubos` was that
the latter is counting # of ubos loaded via `ldg` (based on UBO addrs
in push-consts). But turns out there isn't really any reason to care.
Instead just add an early return in the one code-path that cares about
the number of `ldg` UBOs.
This gets rid of one more thing we need to move from `ir3_shader` to
`ir3_shader_variant`.
