spi: cadence-quadspi: fix clock imbalance on probe failure

commit cba53fe20c18688c17ca668ad0e4ec05e31c70d3 upstream.

Drop the bogus runtime PM get on probe failures that was never needed
and that leaks a usage count reference while preventing the clocks from
being disabled (as runtime PM has not yet been enabled).
