Christophe JAILLET 9fbd8dc19a dma-mapping: use 'bitmap_zalloc()' when applicable ...

'dma_mem->bitmap' is a bitmap. So use 'bitmap_zalloc()' to simplify code,
improve the semantic and avoid some open-coded arithmetic in allocator
arguments.

Also change the corresponding 'kfree()' into 'bitmap_free()' to keep
consistency.
