Remove the entire ib_core_uverbs.c from the build if CONFIG_INFINIBAND_USER_ACCESS is not set. These functions are only used to support uverbs and are never callable even if they happen to get linked in. Provide inlines for the missing ones to return errors to further push code elimination in drivers.

libibverbs, libibcm and a hardware driver library from
