spi: atmel-quadspi: Don't leak clk enable count in pm resume

Browse Source 
[ Upstream commit c18bbac353 ]

The pm resume call is supposed to enable two clocks. If the second enable
fails the callback reports failure but doesn't undo the first enable.

So call clk_disable() for the first clock when clk_enable() for the second
one fails.
