[PATCH v2] bug: make __warn unconditionally defined

[Stephen Zhang]

From: Shida Zhang <zhangshida@xxxxxxxxxx>

__warn() was defined when CONFIG_BUG gets defined originally, but
it was used unconditonally by traps.c. So the idea is to have the
__warn unconditional.

Signed-off-by: Shida Zhang <zhangshida@xxxxxxxxxx>

 Changelog in v1 -> v2:
 - To have the __warn() unconditional instead.
