ASoC: fsl_sai: Fix exiting path on probing failure

Browse Source 
commit d1520889782dff58610c0b6b54d4cf3211ceb690 upstream.

If the imx-sdma driver is built as a module, the fsl-sai device doesn't
disable on probing failure, which causes the warning in the next probing:

==================================================================
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
==================================================================

Disabling the device properly fixes the issue.
