RapidIO/mpc85xx: fix possible mport registration problems
Fix a possible problem with mport registration left non-cleared after fsl_rio_setup() exits on link error. Abort mport initialization if registration failed. This patch is applicable to 2.6.39-rc1 only. The problem does not exist for earlier versions.
