netfilter: nf_ct_expect: remove the redundant slash when policy name is empty
The 'name' filed in struct nf_conntrack_expect_policy{} is not a
pointer, so check it is NULL or not will always return true. Even if the
name is empty, slash will always be displayed like follows:
# cat /proc/net/nf_conntrack_expect
297 l3proto = 2 proto=6 src=1.1.1.1 dst=2.2.2.2 sport=1 dport=1025 ftp/
^
