Clear port pending interrupts before reset, as per AHCI
specifications (Szuying). Followup fixes for this one are to not
clear ATA_PFLAG_EH_PENDING in ata_eh_reset() to allow EH to
continue on with other actions recorded with error interrupts
triggered before EH completes. A~Nd an additional fix to avoid
thawing a port twice in EH (Niklas).
