spi: atmel-quadspi: Disable clock in probe error path
commit 0e685017c7ba1a2fe9f6f1e7a9302890747d934c upstream.
If the call to of_device_get_match_data() fails on probe of the Atmel
QuadSPI driver, the clock "aq->pclk" is erroneously not unprepared and
disabled. Fix it.
Fixes: 2e5c88887358 ("spi: atmel-quadspi: add support for sam9x60 qspi controller")
