libata: fix ehc->i.action setting in ata_eh_autopsy()

ata_eh_autopsy() used to directly assign determined action mask to ehc->i.action thus overriding actions set by some of nested analyze functions. This patch makes ata_eh_autopsy() add action masks just as it's done in other places.

Jeff, this doesn't cause too much trouble but it would be nice to have this fixed in #linus too. Thanks.
