As I can see from the code, two places (tcp_v6_syn_recv_sock and
dccp_v6_request_recv_sock) that call this one already run with
BHs disabled, so it's safe to call __inet_inherit_port there.
Besides (in case I missed smth with code review) the calltrace
tcp_v6_syn_recv_sock
`- tcp_v4_syn_recv_sock
`- __inet_inherit_port
and the similar for DCCP are valid, but assumes BHs to be disabled.
