ide: refactor tf_read() method
Simplify tf_read() method, making it deal only with 'struct ide_taskfile' and the validity flags that the upper layer passes, and factoring out the code that deals with the high order bytes into ide_tf_readback() to be called from the only two functions interested, ide_complete_cmd() and ide_dump_sector(). This should stop the needless code duplication in this method and so make it about twice smaller than it was; along with simplifying the setup for the method call, this should save both time and space...
