rG0de6295af231: powerpc: refactor dmamap setup; free dmamap in error paths
Summary
  • refactor the dmamap allocation / setup path for future code changes to align with arm64 busdma code;
  • free the dmamap allocation if the dma segment list can't be allocated;
  • free the dmamap allocation during the busdma dmamem allocation path if the actual memory allocation itself fails.

Locally tested:

  • POWER9 ppc64le native boot, Raptor Engineering Blackbird
  • POWER8 ppc6le, IBM POWER S822LC
