The coemdi (*insn_read) functions are supposed to read insn->n values

Use the comedi_offset_munge() helper to munge the two's complement
values to offset binary.
My guess would be that the format of the output value could be
controlled by the ME4000_AI_CTRL_BIT_OFFSET bit, but that's only a
guess, and the guy at Meilhaus who wrote the original driver didn't use it!
