cgroup: use assign_bit() where applicable
Convert open-coded if/else with set_bit/clear_bit and their
non-atomic __set_bit/__clear_bit variants to the assign_bit/__assign_bit
API.
Done with Coccinelle semantic patch:
// set_bit -> clear_bit => assign_bit

expression cond, bit, addr;

-if (cond)
- set_bit(bit, addr);
