bpf, docs: Clarify that MOVSX is only for BPF_X not BPF_K
Per discussion on the mailing list at
https://mailarchive.ietf.org/arch/msg/bpf/uQiqhURdtxV_ZQOTgjCdm-seh74/
the MOVSX operation is only defined to support register extension.
The document didn't previously state this and incorrectly implied
that one could use an immediate value.
