gallium/ntt: Drop reindexing of SSA defs and regs. 

It made the nir_print_shader() for NIR_TO_TGSI_DEBUG not match up with the
instructions being emitted, confusing me.  Given that I'm seeing only like
1/3 shrinking in the SSA indices, just drop the reindexing since it's not
doing much (and we don't store that much per SSA index).
