beam_bsm: Eliminate uncovered line in warning generation
In warning_translate_label/2, gb_trees:lookup/2 is called
to translate from the entry label for a function to its name.
Since the gb_tree has an entry for all functions in the module,
there is no way that the lookup can fail unless there is a
serious bug.
Therefore, use gb_trees:get/2 so that an exception and an
internal compiler error will be generated if the lookup would
ever fail.
