[PATCH v2] iio: proximity: aw96103: Fix early return in IRQ handler loop

[Salah Triki]

When an unrecognized proximity status is encountered in aw96103_irq(),
the default case executes a return IRQ_HANDLED. Because this happens
inside the loop over the device's channels, any remaining channels are
left unhandled, causing missed events and stale IRQ status.

Replace the return IRQ_HANDLED statement in the default case with
continue to ensure all channels are processed even if one has an
unexpected status value.

This issue was found via code inspection.
