i2c: ocores: Disable clock on failed resume
ocores_i2c_resume() enables the controller clock before reinitializing
the hardware. If the clock rate changed while the device was suspended,
ocores_init() may reject the resulting prescaler. The callback then
returns an error with the clock still enabled, while the controller
itself remains disabled.
Disable and unprepare the clock when ocores_init() fails so the failed
resume path balances the successful clk_prepare_enable() call.
This issue was found by a static analysis checker and confirmed by manual
source review.
