I2C: OMAP: xfer: fix runtime PM get/put balance on error
In omap_i2c_xfer(), ensure pm_runtime_put() is called, even on
failure.
Without this, after a failed xfer, the runtime PM usecount will have
been incremented, but not decremented causing the usecount to never
reach zero after a failure. This keeps the device always runtime PM
enabled which keeps the enclosing power domain active, and prevents
full-chip retention/off from happening during idle.
