Maximilian Luz 86eb98cb4a platform/surface: aggregator: Fix access of unaligned value
The raw message frame length is unaligned and explicitly marked as
little endian. It should not be accessed without the appropriate
accessor functions. Fix this.

Note that payload.len already contains the correct length after parsing
via sshp_parse_frame(), so we can simply use that instead.
