[PATCH 5/8] omap: iovmm: Add missing mutex_unlock

[tony@atomide.com (Tony Lindgren)]

From: Daniel Walker <dwalker@fifo99.com>

I was using Coccinelle with the mutex_unlock semantic patch, and it
unconvered this problem. It appears to be a valid missing unlock issue.
This change should correct it by moving the unlock below the label.

This patch is against the mainline kernel.
