[libata] ensure ->tf_read() hook reads Status and Error registers

We want ->tf_read() to get a complete snapshot of all taskfile
registers, without requiring the callers to manually call
ata_chk_status() and ata_chk_err() themselves.

This also fixes a minor bug in sata_vsc where the lower bits of the
feature register were incorrectly placed in the HOB (high order bits)
portion of struct ata_taskfile.
