[Tests] Fixup duplicated mrope logic

[vasqu]

Rebase/merge didnt remove the logic in #40490 because they were done at 2 different lines in the code

Other logic is a few lines down

transformers/tests/test_modeling_common.py

Lines 4792 to 4798 in 8564e21

	# 3d rope also depends on the head dim
	# (we assume easy shapes here where we get to the requested head dim at least)
	if hasattr(config, "rope_scaling") and len(config.rope_scaling.get("mrope_section", None)) > 0:
	scaling_factor = max(requested_dim // (sum(config.rope_scaling["mrope_section"]) * 2), 1)
	config.rope_scaling["mrope_section"] = [
	section * scaling_factor for section in config.rope_scaling["mrope_section"]
	]

Seems like the failed tests are the same as in main, ie CI is currently broken
