b43legacy: fix DMA for 30/32-bit DMA engines

Browse source

This checks if the DMA address is bigger than what the controller can manage.
It will reallocate the buffers in the GFP_DMA zone in that case.

The patch by Michael Buesch has been ported to b43legacy.
Thanks to Matti Viljanen for reporting this.
