x86: remove printk() from init_timer()

For console drivers which use udelay() we can deadlock
in the printk path on the spinlock. The reason is that
on the first call to udelay() from within a console driver
it will go back down the printk() path deadlocking oneself.

Just remove the printk() as it was asymmetric on romstage
vs ramstage.
