debugobjects: Avoid another unused variable warning
debug_objects_maxchecked is only updated in __debug_check_no_obj_freed(),
and only read in debug_objects_maxchecked, unfortunately both of these are
optional and depend on different Kconfig symbols.
When both CONFIG_DEBUG_OBJECTS_FREE and CONFIG_DEBUG_FS are disabled this
warning is emitted:
lib/debugobjects.c:56:14: error: 'debug_objects_maxchecked' defined but not used [-Werror=unused-variable]
Rather than trying to add more complex #ifdef protections, mark the
variable as __maybe_unused so it can be silently dropped when usused.
Fixes: bd9dcd046509 ("debugobjects: Export max loops counter")
