netlink_delinearize: allow postprocessing on concatenated elements

Currently there is no case where the individual expressions inside a
mapped concatenation need to be munged.

However, to support proper delinearization for an input like
'rule netdev nt nc set update ether saddr . vlan id timeout 5s @macset'

we need to allow this.

Right now, this gets listed as:

update @macset { @ll,48,48 . @ll,112,16 & 0xfff timeout 5s }

because the ethernet protocol is replaced by vlan beforehand,
so we fail to map @ll,48,48 to a vlan protocol.

Likewise, we can't map the vlan info either because we cannot
cope with the 'and' operation properly, nor is it removed.

Prepare for this by deleting and re-adding so that we do not
corrupt the linked list.

After this, the list can be safely changed and a followup patch
can start to delete/reallocate expressions.
