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.
