It's very likely that the configured data transfer mode is the wrong
one if device fails data transfers right after initial data transfer
mode configuration (including NCQ on/off and xfermode). libata EH
needs to speed down fast before upper layers give up on probing.
This patch implement fast speed down rules to handle such cases
better. Error occured while data transfer hasn't been verified
trigger fast back-to-back speed down actions until data transfer
works.
This change will make cable mis-detection and other initial
configuration problems corrected before partition scanning code gives
up.
