staging: comedi: ni_mio_common: remove variable 'dl' in ni_ai_insn_read()
In `ni_ai_insn_read()`, local variable `dl` is declared as `unsigned
long`, but `unsigned int` will do. Get rid of it and use local variable
`d` instead. (That used to be `unsigned short`, but has been `unsigned
int` since kernel version 3.18.)
