padata: Remove cpu online check from cpu add and removal
During the CPU offline process, the dying CPU is cleared from the
cpu_online_mask in takedown_cpu(). After this step, various CPUHP_*_DEAD
callbacks are executed to perform cleanup jobs for the dead CPU, so this
cpu online check in padata_cpu_dead() is unnecessary.
Similarly, when executing padata_cpu_online() during the
CPUHP_AP_ONLINE_DYN phase, the CPU has already been set in the
cpu_online_mask, the action even occurs earlier than the
CPUHP_AP_ONLINE_IDLE stage.
Remove this unnecessary cpu online check in __padata_add_cpu() and
__padata_remove_cpu().
