Guennadi Liakhovetski 91ab252ac5 mmc: sh-mmcif: avoid oops on spurious interrupts (second try)
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.
