inet: Fix __inet_inherit_port() to correctly increment bsockets and num_owners
inet sockets corresponding to passive connections are added to the bind hash
using ___inet_inherit_port(). These sockets are later removed from the bind
hash using __inet_put_port(). These two functions are not exactly symmetrical.
__inet_put_port() decrements hashinfo->bsockets and tb->num_owners, whereas
___inet_inherit_port() does not increment them. This results in both of these
going to -ve values.
This patch fixes this by calling inet_bind_hash() from ___inet_inherit_port(),
which does the right thing.
'bsockets' and 'num_owners' were introduced by commit a9d8f9110d7e953c
(inet: Allowing more than 64k connections and heavily optimize bind(0))
