scottl c5cc3acad0 In _bus_dmamap_load_buffer(), only count the number of bounce pages needed if
they haven't been counted before.  This test was ommitted when bus_dmamap_load()
was merged into this function, and results in the pagesneeded field growing
without bounds when multiple deferrals happen.

Thanks to Paul Saab for beating his head against this for a few hours =-)
