Stefano Brivio 8dd0100ce9 b43legacy: fix DMA slot resource leakage 
This fixes four resource leakages.
In any error path we must deallocate the DMA frame slots we
previously allocated by request_slot().
This is done by storing the ring pointers before doing any ring
allocation and restoring the old pointers in case of an error.

This patch by Michael Buesch has been ported to b43legacy.
