Guennadi Liakhovetski 719740d5de mmc: sh-mmcif: avoid oops on spurious interrupts 
commit 8464dd52d3 upstream.

On some systems, e.g., kzm9g, MMCIF interfaces can produce spurious
interrupts without any active request. To prevent the Oops, that results
in such cases, don't dereference the mmc request pointer until we make
sure, that we are indeed processing such a request.
