When there is memory pressure, at resume time dma_alloc_coherent() returns error which in turn fails the loading of the firmware and hence the driver crashes.

Fix it by allocating only once and then reuse the same allocated memory. As we'll allocate this memory only once, this memory will stays allocated.
