Prashanth K b2c898469d usb: xhci: Add error handling in xhci_map_urb_for_dma 
[ Upstream commit be95cc6d71dfd0cba66e3621c65413321b398052 ]

Currently xhci_map_urb_for_dma() creates a temporary buffer and copies
the SG list to the new linear buffer. But if the kzalloc_node() fails,
then the following sg_pcopy_to_buffer() can lead to crash since it
tries to memcpy to NULL pointer.

So return -ENOMEM if kzalloc returns null pointer.

Cc: stable@vger.kernel.org # 5.11
Fixes: 2017a1e58472 ("usb: xhci: Use temporary buffer to consolidate SG")
