arm/dts: hammerhead: Remove erroneous qcom,msm-bus,active-only property

qcom,msm-bus,active-only is a boolean and not an integer. As a
result, setting "active-only = <0>" was actually enabling it.

Reference: kernel_msm, commit ba514f1fc.

Bluetooth: fix possible info leak in bt_sock_recvmsg()

In case the socket is already shutting down, bt_sock_recvmsg() returns
with 0 without updating msg_namelen leading to net/socket.c leaking the
local, uninitialized sockaddr_storage variable to userland -- 128 bytes
of kernel stack memory.

Fix this by moving the msg_namelen assignment in front of the shutdown
test.
