nf_ct_tuple_src_equal() and nf_ct_tuple_dst_equal() both compare the protocol
numbers. Unfortunately gcc doesn't optimize out the second comparison, so
remove it and prefix both functions with __ to indicate that they should not
be used directly.
Saves another 16 byte of text in __nf_conntrack_find() on x86_64:
nf_conntrack_tuple_taken | -20 # 320 -> 300, size inlines: 181 -> 161
__nf_conntrack_find | -16 # 267 -> 251, size inlines: 127 -> 115
__nf_conntrack_confirm | -40 # 875 -> 835, size inlines: 570 -> 537
3 functions changed, 76 bytes removed
