[PATCH nf-next] netfilter: nf_defrag_ipv4: Drop redundant ip_send_check()

[Joe Stringer]

Since commit 0848f6428ba3 ("inet: frags: fix defragmented packet's IP
header for af_packet"), ip_send_check() would be called twice for
defragmentation that occurs from netfilter ipv4 defrag hooks. Remove the
extra call.
