Command-line arguments used

Steps to reproduce

As mentioned in #969 (comment)

Non-runtime applications of LoRA in Vulkan now fail with an assert in ggml_vk_mul_mat_q_f16
This even applies when wtype is set to q4_0 which worked before

ggml/src/ggml-vulkan/ggml-vulkan.cpp:6552: GGML_ASSERT(y_non_contig || !qy_needs_dequant) failed
both my lora and model are .safetensors, runtime converted to q4_0
model is a SDXL model.
previously, this combination worked fine. running in immediate mode works, though.

What you expected to happen

LoRA applied successfully

What actually happened

GGML Assert occurred. Reproducible by @wbruna
