Haoxiang Li b662f91e21 bus: fsl-mc: fix an error handling in fsl_mc_device_add() 
[ Upstream commit 52f527d091 ]

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.

Fixes: bbf9d17d98 ("staging: fsl-mc: Freescale Management Complex (fsl-mc) bus driver")
