Subject: [PATCH v3 11/20] remoteproc: core: Correction carveout name comparison in rproc_update_resource_table_entry

As old and new carveout name length may be different and the two
names may have a common part, name comparison must cover the complete
name field.
Limit strncmp to carveout name length, i.e. 32 Bytes.
