USB: xhci: Fix bug memory free after failed initialization.

commit d94c05e33d9212ee67b8d4998f984cc71df8168b upstream.

If the xHCI driver fails during the memory initialization, xhci->ir_set
may not be a valid pointer.  Check that it points to valid DMA'able memory
before writing to that address during the memory freeing process.
