bus: fsl-mc: Fix potential double device reference in fsl_mc_get_endpoint()
commit bddbe13d36a02d5097b99cf02354d5752ad1ac60 upstream.
The fsl_mc_get_endpoint() function may call fsl_mc_device_lookup()
twice, which would increment the device's reference count twice if
both lookups find a device. This could lead to a reference count leak.
Found by code review.
