[PATCH] the latest consensus libata resume fix

Okay, just to sum things up.

This forces libata to wait for up to 2 seconds for BUSY|DRQ to clear
on resume before continuing.

[jgarzik adds...]  During testing we never saw DRQ asserted, but
nonetheless (a) this works and (b) testing for DRQ won't hurt.
