[PATCH] core: Fix wrong expectations for the return of recv()

[Vinicius Costa Gomes <vcgomes@gmail.com>]

Since commit b5f34f9420b50 "Bluetooth: Fix bt_sock_recvmsg return value"
in the kernel, Bluetooth sockets of type SOCK_SEQPACKET, when read()
will return the size of the packet received, which can be larger than
the the buffer passed by user space.

In this case the problem was causing a disconnection soon after
the reception of an SDP request.
