freedreno/ir3: fix error in bail logic
all_delayed will also be true if we didn't attempt to schedule anything
due to no more instructions using current addr/pred. We rely on coming
in to block_sched_undelayed() to detect and clean up when there are no
more uses of the current addr/pred, which isn't necessarily an error.
This fixes a regression introduced in b823abed.
