[PATCH v4 7/9] iio: light: opt3001: mark the interrupt handler __context_unsafe

[Rupesh Majhi]

opt3001_irq() takes opt->lock only when ok_to_ignore_lock is false, and
releases it under the same test. Context analysis does not follow a
lock taken and released on a condition, so mark the handler
__context_unsafe().
