[PATCH] bus: mvebu-mbus: fix iounmap() in error path

[Luis Henriques <henrix@camandro.org>]

This patch fixes the following Coccinelle error:

./drivers/bus/mvebu-mbus.c:1115:2-8: \
	ERROR: missing iounmap; ioremap on line 1108 \
	and execution via conditional on line 1113

Although all mvebu_mbus_common_init() callers seem to actually use
&mbus_state in the 1st argument, this is still a bug that could be
triggered by future changes.
