panfrost: Drop initial mali_attr_meta.src_offset assignment

The mali_attr_meta.src_offset is initialized to
pipe_vertex_element.src_offset at vertex element creation time, but
this field is then adjusted when the descrptors are emitted. Let's
use the pipe_vertex_element data we saved earlier and drop this initial
assignment.
