Subject: alpha: fix formating of stack content

From: Mikulas Patocka <mpatocka@redhat.com>

commit 4b01abdb32fc36abe877503bfbd33019159fad71 upstream.

Since version 4.9, the kernel automatically breaks printk calls into
multiple newlines unless pr_cont is used. Fix the alpha stacktrace code,
so that it prints stack trace in four columns, as it was initially
intended.
