Subject: sh: move defines needed for suppressing warning backtraces
Date: Thu, 13 Mar 2025 11:43:27 +0000

Declaring the defines needed for suppressing warning inside
'#ifdef CONFIG_DEBUG_BUGVERBOSE' results in a kerneldoc warning.

.../bug.h:29: warning: expecting prototype for _EMIT_BUG_ENTRY().
	Prototype was for HAVE_BUG_FUNCTION() instead

Move the defines above the kerneldoc entry for _EMIT_BUG_ENTRY
to make kerneldoc happy.
