As already discussed in the previous change which introduced BPF_RUN_PROG_PIN_ON_CPU() BPF only requires to disable migration to guarantee per CPUness. If RT substitutes the preempt disable based migration protection then the cant_sleep() check will obviously trigger as preemption is not disabled. Replace it by cant_migrate() which maps to cant_sleep() on a non RT kernel and will verify that migration is disabled on a full RT kernel.
