memory: emif: Add check for setup_interrupts
[ Upstream commit fd7bd80b46373887b390852f490f21b07e209498 ]
As the potential failure of the devm_request_threaded_irq(),
it should be better to check the return value of the
setup_interrupts() and return error if fails.
Fixes: 68b4aee35d1f ("memory: emif: add interrupt and temperature handling")
