hw/ptimer: Actually stop the timer in case of error

Running with counter / period = 0 is treated as a error case, printing error
message claiming that timer has been disabled. However, timer is only marked
as disabled, keeping to tick till expired and triggering after being claimed
as disabled. Stop the QEMU timer to avoid confusion.
