[LU-13152] llapi layout llc_pattern is not set properly on DoM component

Description

The function llapi_layout_get_by_xattr does not set the llc_pattern of a DoM component to LLAPI_LAYOUT_MDT but to LOV_PATTERN_MDT. This causes the function llapi_layout_pattern_set to fail because it is expecting one of the LLAPI_LAYOUT values.

I'm attaching a simplistic patch to explain.
