printk: Fix "printk: Enable the use of more than one CON_BOOT (early console)"

Don't return when we find the first bootconsole - it can leave
other bootconsoles still installed, and they can be used and
cause problems later (if they are in the init section, and
eventually released), and cause problems.  Make sure we remove
all of them.
