scsi: iscsi_tcp: restrict to TCP sockets



Nothing prevents iscsi_sw_tcp_conn_bind() to receive file descriptor
pointing to non TCP socket (af_unix for example).

Return -EINVAL if this is attempted, instead of crashing the kernel.

Fixes: 7ba24713 ("[SCSI] open-iscsi/linux-iscsi-5 Initiator: Initiator code")
