nfp: bpf: add map deletes from the datapath

Browse source

Support calling map_delete_elem() FW helper from the datapath
programs.  For JIT checks and code are basically equivalent
to map lookups.  Similarly to other map helper key must be on
the stack.  Different pointer types are left for future extension.
