[Openais] [openais-whitetank patch] fix lib_exit returning -1 to work properly

[Steven Dake]

When lib_exit returns -1 (indicating the totem queue is full and unable
to send new messages), the ipc system should allow the transmission of
totem messages in this condition.  However, with the current code, a
global lock is held during this period, locking out the ability to send
totem messages and resulting in a repeating loop if lib_exit_fn returns
-1 because it expects totem message queue space to become available.

Patch attached to fix.
