drive_is_ready() reads STATUS register if CONFIG_IDEPCI_SHARE_IRQ is not
defined and ALTSTATUS register if it is defined.  Therefore drive_is_ready()
in pre_task_mulout_intr() only makes sense if we can't trust STATUS register
(because we call ide_wait_stat() which reads STATUS register earlier).

Remove this "workaround" for now as it is not present in ide-disk.c
and whole multi PIO-out code (CONFIG_IDE_TASKFILE_IO=n) was buggy before.
