media: cadence: csi2rx: Fix csi2rx_start error handling
The clocks enabled by csi2rx_start function are intended to be disabled in
an error path but there are two issues:
1) the loop condition is always true and
2) the first clock disabled is the the one enabling of which failed.
Fix these two bugs by changing the loop condition as well as only disabling
the clocks that were actually enabled.
