[PATCH] libata: implement ata_eh_wait()
Implement ata_eh_wait(). On return from this function, it's
guaranteed that the EH which was pending or in progress when the
function was called is complete - including the tailing part of SCSI
EH. This will be used by hotplug and others to synchronize with EH.
