ksmbd: off ipv6only for both ipv4/ipv6 binding
commit cc00bc83f26eb8f2d8d9f56b949b62fd774d8432 upstream.
ΕΛΕΝΗ reported that ksmbd binds to the IPV6 wildcard (::) by default for
ipv4 and ipv6 binding. So IPV4 connections are successful only when
the Linux system parameter bindv6only is set to 0 [default value].
If this parameter is set to 1, then the ipv6 wildcard only represents
any IPV6 address. Samba creates different sockets for ipv4 and ipv6
by default. This patch off sk_ipv6only to support IPV4/IPV6 connections
without creating two sockets.
