USB: uas: Use GFP_NOIO instead of GFP_KERNEL in I/O submission path
If swap is on a UAS device, we could recurse into the driver by using GFP_KERNEL. Using GFP_NOIO ensures we won't. Reported-by: James Bottomley <James.Bottomley@suse.de> Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
