genirq: Don't overwrite interrupt thread flags on setup
Chris reported that the recent affinity management changes result in
overwriting the already initialized thread flags.
Use set_bit() to set the affinity bit instead of assigning the bit value to
the flags.
Fixes: 801afdfbfcd9 ("genirq: Fix interrupt threads affinity vs. cpuset isolated partitions")
