[PATCH net-next 14/14] mptcp: Remove unnecessary test for __mptcp_init_sock()

From: Kuniyuki Iwashima <kuniyu@amazon.com>

__mptcp_init_sock() always returns 0 because mptcp_init_sock() used
to return the value directly.

But after commit 18b683bff89d ("mptcp: queue data for mptcp level
retransmission"), __mptcp_init_sock() need not return value anymore.

Let's remove the unnecessary test for __mptcp_init_sock() and make
it return void.
