Dan Carpenter d00b0d1cdc ALSA: usb-audio: Fix a DMA to stack memory bug 
commit f7d306b47a24367302bd4fe846854e07752ffcd9 upstream.

The usb_get_descriptor() function does DMA so we're not allowed
to use a stack buffer for that.  Doing DMA to the stack is not portable
all architectures.  Move the "new_device_descriptor" from being stored
on the stack and allocate it with kmalloc() instead.

Fixes: b909df18ce2a ("ALSA: usb-audio: Fix potential out-of-bound accesses for Extigy and Mbox devices")
