Moved definition of ucBufferStorage out of if macro. (#459)

* Moved definition of ucBufferStorage out of if macro. If ucBufferStorage is only defined when configSUPPORT_STATIC_ALLOCATION ist set to 1, compilation will fail in cases where it is set to 0 or not defined (because it defaults to 0, as described in the documenation).
