net/bluetooth: fix null pointer dereference in bluetooth_sendmsg

Browse source 
Move the NULL check for radio pointer before the DEBUGASSERT that
dereferences it. Previously DEBUGASSERT(radio->r_dev.d_lltype == ...)
was executed before verifying radio != NULL, which would crash when
the device is not found.
