John Ogness a2e14cc2da printk: For @suppress_panic_printk check for other CPU in panic

[ Upstream commit 0ab7cdd00491b532591ef065be706301de7e448f ]

Currently @suppress_panic_printk is checked along with
non-matching @panic_cpu and current CPU. This works
because @suppress_panic_printk is only set when
panic_in_progress() is true.

Rather than relying on the @suppress_panic_printk semantics,
use the concise helper function other_cpu_in_progress(). The
helper function exists to avoid open coding such tests.
