[PATCH V2] libata:fix kernel panic when hotplug

From: Ding Xiang In normal condition,if we use sas protocol and hotplug a sata disk on a port,the sas driver will send event "PORTE_BYTES_DMAED" and call function "sas_porte_bytes_dmaed". But if a sata disk is run io and unplug it,then plug a new sata disk,this operation may cause a kernel panic
