subdev_8255_init() can fail, make sure to check for it and return
the errno.

The private function subdev_8255_cb() is identical to the default
io callback used by the 8255 driver. Remove it and pass NULL to
subdev_8255_init() so the default callback will be used.

The private function subdev_8255mapped_cb() is used for the memory
memory mapped io of the pet48dio board. Rename this function so
it has namespace associated with the driver.

Casting the iobase passed to subdev_8255_init() is not needed.
Use a local variable for the iobase and remove the casts.

ft1000dev->tx_urb and ft1000dev->rx_urb are not deallocated
if something goes wrong in ft1000_probe(). Also there is no
check for success of urb allocation. The patch fixes the both issues.

By the way, there is no sense in GFP_ATOMIC for urb allocation here,
so it is changed to GFP_KERNEL.
