libata: fix EH action overwriting in ata_eh_reset()
ehc->i.action got accidentally overwritten to ATA_EH_HARD/SOFTRESET in
ata_eh_reset(). The original intention was to clear reset action
which wasn't selected. This can cause unexpected behavior when other
EH actions are scheduled together with reset. Fix it.
