Johan Hovold 90e176b3e7 soc: qcom: ocmem: fix device leak on lookup 
commit b5c16ea57b upstream.

Make sure to drop the reference taken to the ocmem platform device when
looking up its driver data.

Note that holding a reference to a device does not prevent its driver
data from going away so there is no point in keeping the reference.

Also note that commit 0ff027027e ("soc: qcom: ocmem: Fix missing
put_device() call in of_get_ocmem") fixed the leak in a lookup error
path, but the reference is still leaking on success.
