dma-mapping: use dma_get_mask in dma_addressing_limited
We currently have cases where the dma_addressing_limited() gets
called with dma_mask unset. This causes a NULL pointer dereference.
Use dma_get_mask() accessor to prevent the crash.
Fixes: b866455423e0 ("dma-mapping: add a dma_addressing_limited helper")
