[PATCH] Move command descriptor setup to seperate function as preparation

[Evgeniy Polyakov <zbr@ioremap.net>]

From: Patrick McHardy <kaber@trash.net>

Note 1: also fix a harmless typo while moving it: sa_idx is initialized
	to dma->resi instead of dma->cmdi.

Note 2: errors from command descriptor setup are not propagated back,
	anymore, they can't be handled anyway and all conditions leading
	to errors should be checked earlier.
