xhci: remove GFP_DMA flag from allocation
commit 5db851cf20857c5504b146046e97cb7781f2a743 upstream.
There is no reason to restrict allocations to the first 16MB ISA DMA
addresses.
It is causing problems in a virtualization setup with enabled IOMMU
(x86_64). The result is that USB is not working in the VM.
