ide: fix ->io_32bit race in ide_taskfile_ioctl() ...
In ide_taskfile_ioctl(), there was a race condition involving
drive->io_32bit. It was cleared and restored during ioctl
requests but there was no synchronization with other requests.
So, other requests could execute with the altered ->io_32bit
setting or updated drive->io_32bit could be overwritten by
ide_taskfile_ioctl().
This patch adds IDE_TFLAG_IO_16BIT flag to indicate to
ide_pio_datablock() that 16-bit I/O is needed regardless of
drive->io_32bit settting.
