libata: kill now unused n_iter and fix sata_fsl

qc->n_iter was used for libata's own sg walking before sg chaining
replaced it.  During conversion, the field and its usage in sata_fsl
were left behind.  Kill the filed and update sata_fsl.

tj: This was part of James's libata-use-block-layer-padding patch.
    Separated out by me.
