Context information structures are protected by a mutex that is held
when accessing/manipulating the context. When the code that manages
these structures was authored, a decision was made to include taking
the mutex as part of the allocation/initialization sequence and also
handle the scenario where the mutex was already held when freeing the
context.

While not a problem outright, this design decision has been deemed as
too flexible and the code should be made more rigid to avoid future bugs.
In addition, further review of the code yields that the existing mutex
manipulations in both of these context management paths are superfluous.

This commit removes the obtaining of the context mutex in the context
initialization routine and assumes the mutex is not held in the context
free path.
