ASoC: mt6660: Fix PM disable depth imbalance in mt6660_i2c_probe

[ Upstream commit b73f11e895e140537e7f8c7251211ccd3ce0782b ]

The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context. We fix it by moving
pm_runtime_enable to the endding of mt6660_i2c_probe.
