[PATCH 04/12] mmc: omap_hsmmc: release correct resource

[Russell King]

res can be one of several resources, as this variable is re-used several
times during probe.  This can cause the wrong resource parameters to be
passed to release_mem_region().

Get the original memory resource before calling release_mem_region().
