[libata] Fix reported task file values in sense data
ata_tf_read was setting HOB bit when lba48 command was submitted, but was not clearing it before reading "normal" data. As it is only place which sets HOB bit in control register, and register reads should not be affected by other bits, let's just clear it when we are done with reading upper bytes so non-48bit commands do not have to touch ctl at all. pata_scc suffered from same problem...
