Setting an SF on an SFP hop with an SF type different than the corresponding SFC hop should fail

If an SFC is defined as follows:

SFC-1
[Firewall, TcpProxy, DPI]

And an SFP is defined using that SFC, as follows:

SFP (uses SFC-1]
[SF of type NAT, SF of type Header Enrichment, SF of type Firewall]

Notice that the SF types at each hop are of a different type than specified in the SFC, then there should be a failure, but there is none.

A correct SFP would be as follows:

SFP (uses SFC-1)
[SF1 of type Firewall, SF2 of type TcpProxy, SF3 of type DPI]
