staging: comedi: jr3_pci: check sizes at compile time
The driver currently checks the size of `struct jr3_sensor` is correct
when a device is attached, returning an error if it is wrong. Replace
that with a compile-time check. We don't care too much about the size
of `struct jr3_sensor` as it is embedded in the larger `struct
jr3_block` and is followed by a lot of padding. We should care more
that the size of `struct jr3_block` is correct, as it describes the
overall register layout of a block, and there is an array of such blocks
(one per subdevice). Check its size at compile-time using the
`BUILD_BUG_ON()` macro.
