Subject: staging: fsl-mc-bus: fix build warning

Git-commit: fb17be96eed821f60670adf1748afb3d57fe63bb
Patch-mainline: v4.16-rc1
References: fate#326530,fate#326531,fate#326535,fate#326538,fate#326539

error could be unitialized when it is used as a return value in
fsl_mc_device_add().  So fix up the warning by properly setting it.
