mutex memory leak in ph7_vm_release (with patch)

[tarkin000]

Latest clone, on Debian 7 i686 (x32), gcc 4.7.2 (Debian 4.7.2-5)
-DPH7_ENABLE_MATH_FUNC -DPH7_ENABLE_THREADS

Valgrind reports a definite memory loss of 112 bytes.
The loss starts when a recursive mutex is created in ProcessScript (60601).
When ph7_vm_release is called, the mutex is not released.

This patch fixes that.

Hope this helps.
