kernel: Allow queue_wait_w_tmo() to be called with TIMEOUT_BLOCK.
Previously TIMEOUT_BLOCK would be handled the same as TIMEOUT_NOBLOCK, i.e.
poll only without thread switch, which is rather unexpected from *_w_tmo()
functions. No current code doesn't call it that way yet.
Change-Id: I370ce0f752681122d197eadeee9ab17112647c20
