USB: xhci: Use GFP_ATOMIC while holding spinlocks.

The xHCI functions to queue an URB onto the hardware rings must be called
with the xhci spinlock held.  Those functions will allocate memory, and
take a gfp_t memory flags argument.  We must pass them the GFP_ATOMIC
flag, since we don't want the memory allocation to attempt to sleep while
waiting for more memory to become available.
