Add a check on the optional rproc->cached_table to perform the memory copy only if it is not null.
2 use cases to support: - starting on boot, in which case rproc->cached_table can be null, - starting on crash recovery, where the cached table is used to save the resource table configuration on stop and re-apply the configuration on the re-start.
