MIPS: Fix printk continuations in cpu-bugs64.c

Browse source 
64-bit pre-r6 kernels output the following broken printk continuation
lines during boot:

Checking for the multiply/shift bug...
no.
Checking for the daddiu bug...
no.
Checking for the daddi bug...
no.

Fix the printk continuations in cpu-bugs64.c to use pr_cont to restore
the correct output:

Checking for the multiply/shift bug... no.
Checking for the daddiu bug... no.
Checking for the daddi bug... no.
