Kernel: Fix a few Thread::block related races

Browse Source 
We need to have a Thread lock to protect threading related
operations, such as Thread::m_blocker which is used in
Thread::block.

Also, if a Thread::Blocker indicates that it should be
unblocking immediately, don't actually block the Thread
and instead return immediately in Thread::block.
