pwm: atmel-tcb: Don't check the return code of pwmchip_remove() 



pwmchip_remove() returns always 0. Don't use the value to make it
possible to eventually change the function to return void. Also the
driver core ignores the return value of atmel_tcb_pwm_remove()
and considers the device removed anyhow. So returning early results in a
resource leak.
