media: rcar_fdp1: Fix the correct variable assignments

In the function fdp1_probe(), when get irq failed, the
function platform_get_irq() log an error message, so
remove redundant message here. And the variable type
of "ret" is int, the "fdp1->irq" is unsigned int, when
irq failed, this place maybe wrong, thus fix it.
