MIPS: Fix printk continuations in cpu-bugs64.c
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.
