bus: fsl-mc: fix an error handling in fsl_mc_device_add()

[ Upstream commit 52f527d0916bcdd7621a0c9e7e599b133294d495 ]

In fsl_mc_device_add(), device_initialize() is called first.
put_device() should be called to drop the reference if error
occurs. And other resources would be released via put_device
-> fsl_mc_device_release. So remove redundant kfree() in
error handling path.
