Commit e1d9a90a9bfd ("net: ethernet: rmnet: Support for ingress MAPv5 checksum offload") broke ingress handling for devices where RMNET_FLAGS_INGRESS_MAP_CKSUMV5 or RMNET_FLAGS_INGRESS_MAP_CKSUMV4 are not set. Unless either of these flags are set, the MAP header is not removed. This commit restores the original logic by ensuring that the MAP header is removed for all MAP packets.
