ir3: fix clearing merge sets after shared RA

Browse Source 
After spilling during regular RA, merge sets need to be fixed up. To
find all merge sets, fixup_merge_sets used ra_foreach_dst. However,
after shared RA has run, shared dsts wouldn't have the IR3_REG_SSA flag
set anymore leaving their merge sets lingering. This patch fixes this by
using foreach_dst instead.
