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. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
