rin aba664485b Audit unload/unmap v.s. free against DMA buffer for sys/dev; 
make sure that bus_dmamap_unload(9) [or bus_dmamap_destroy(9)] or
bus_dmamem_unmap(9) are preceding to freeing DMA buffer, if it is
loaded or mapped, respectively.

This is mandatory for some archs. See, e.g.:

For some drivers, resource leaks for error paths are fixed at
the same time.

Compile test only (at least one arch per driver).
