[PATCH 09/14] ide: inline task_in_unexpected() into task_pio_intr()

[Bartlomiej Zolnierkiewicz]

From: Bartlomiej Zolnierkiewicz <bzolnier@xxxxxxxxx>
Subject: [PATCH] ide: inline task_in_unexpected() into task_pio_intr()

task_in_unexpected() is only used by task_pio_intr() so inline it there.

There should be no functional changes caused by this patch.
