netfilter: conntrack: avoid unneeded nf_conntrack_l4proto lookups
after removal of the packet and invert function pointers, several
places do not need to lookup the l4proto structure anymore.
Remove those lookups.
The function nf_ct_invert_tuplepr becomes redundant, replace
it with nf_ct_invert_tuple everywhere.
