[LEDE-DEV] [PATCH] ar71xx: spi-rb4xx: balance clk_prepare_enable() call

[Gabor Juhos]

Commit c312cef223dd ("ar71xx: spi-rb4xx fix.") replaced the clk_enable() call
with clk_prepare_enable() to meet the common clock framework requirements.
However it did not change the clk_disable() call in the error patch which
thus leads to imbalance.

Fix the code by using the correct counterpart of clk_prepare_enable() in both
places.
