printk: Don't try to parse DEVNAME:0.0 console options

Browse Source 
Currently console_setup() tries to make a console index out of any digits
passed in the kernel command line for console. In the DEVNAME:0.0 case,
the name can contain a device IO address, so bail out on console names
with a ':'.
