When the taskq implementation was originally written I wrapped all
the API functions in #define's. This was done as a preventative
measure to ensure that a taskq symbol never conflicted with an
existing kernel symbol.
However, in practice the taskq symbols never conflicted. The only
major conflicts occured with the kmem cache API. Since this added
layer of obfuscation never bought us anything for the taskq's I'm
removing it.
