[core] Fixed THREAD_STATE_INIT usage in CRcvQueue.

[maxsharabayko]

The CRcvQueue::m_counter variable is shared between threads. The THREAD_STATE_INIT macro used the value to form the thread name, but the value could be the same for several threads.
The thread must already have a name set via ThreadName. Therefore just extract it via ThreadName::get(std::string&).

Fixes #2973.

Is the distinction between LOGGING/!not LOGGING required, since it is handled in ::init already?
Shouldn't the same fix be applied to the SndQ as well?

You are right. Fixed in the second commit.
