staging: comedi: ni_mio_common: always lock in ni_ai_poll()
`ni_ai_poll()` currently acquires (and later releases) the comedi
device's spin-lock iff `in_interrupt()` returns 0. However, it is only
called during processing of a `COMEDI_POLL` ioctl so `in_interrupt()`
will always return 0 in this case. Remove this test and acquire/release
the spin-lock unconditionally. This eliminates a sparse warning about
different lock contexts for basic block.
