[PATCH 59/61] debugobjects: Drop likely() around !IS_ERR_OR_NULL()

Philipp Hahn

IS_ERR_OR_NULL() already uses likely(!ptr) internally. checkpatch does
not like nesting it:
> WARNING: nested (un)?likely() calls, IS_ERR_OR_NULL already uses
> unlikely() internally
Remove the explicit use of likely().
