libata: fix EH-related lockup by properly cleaning EH command list
Yet another hack due to the fact that libata is the only user of SCSI's
->eh_strategy_handler() hook.

[PATCH] sata: fix sata_sx4 dma_prep to not use sg->length
sata_sx4 directly references sg->length to calculate total_len in
pdc20621_dma_prep(). This is incorrect as dma_map_sg() could have
merged multiple sg's into one and, in such case, sg->length doesn't
reflect true size of the entry. This patch makes it use
sg_dma_len(sg).
