gallium/ttn: don't upset nir_validate w/ BRK's
Previously we were unconditionally doing ttn_get_src() even for
instructions with no src's. Which created a lot of unnecessary
load_const instructions. These were mostly harmless since NIR opt
passes would strip them back out. But for an ENDIF following a
BRK, it would result in load_const instructions created after the
NIR break instruction. Which nir_validate dislikes.
But we can actually just dtrt by using NumSrcRegs instead.
