panvk: ensure wsi memory is bound at offset 0

Browse source 
No apps or tests have hit the spec corner case yet, but in theory they
could pass invalid offset and expect the impl to ignore it for wsi alias
binding. This change ensures the offset is zero, which aligns with
common wsi side binding as well as obeying the dedicated allocation
requirement.
