doc: announce renaming of mbuf offload flags

Browse Source 
The mbuf offload flags do not match the DPDK namespace (they are
not prefixed by RTE_). Announce their rename in 21.11, and the
removal of the old names in 22.11.

A draft coccinelle script is provided to anticipate what the
renaming will be.
