staging:iio: core. Allow for event chrdev obtaining ioctl if no buffer present.
Logic bug meant the chrdev would fail to open if there was no buffer support
in a driver or in the core. This meant the ioctl to get the event chrdev
would fail and hence events were not available.
V2: change error to -EINVAL to mark as unsuitable for reading rather than
not there. Both are true depending on how you look at it.
