Subject: devres: fix a for loop bounds check

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 1f35d04a02a652f14566f875aef3a6f2af4cb77b upstream.

The iomap[] array has PCIM_IOMAP_MAX (6) elements and not
DEVICE_COUNT_RESOURCE (16).  This bug was found using a static checker.
It may be that the "if (!(mask & (1 << i)))" check means we never
actually go past the end of the array in real life.
