Yousef Alhouseen d401772a9e misc: genwqe: handle a first DMA address of zero ...

genwqe_setup_sgl() uses zero as the initial previous DMA address. DMA
address zero is valid, so a first entry at that address enters the
merge path before last_s has been assigned and dereferences NULL.

Only merge adjacent mappings after an SGL data entry has been created.
