USB: FHCI: cq_get() should check kfifo_out()'s return value
Since commit 7acd72eb ("kfifo: rename kfifo_put... into kfifo_in... and kfifo_get... into kfifo_out..."), kfifo_out() is marked __must_check, and that causes gcc to produce lots of warnings like this: CC drivers/usb/host/fhci-mem.o In file included from drivers/usb/host/fhci-hcd.c:34: drivers/usb/host/fhci.h: In function 'cq_get': drivers/usb/host/fhci.h:520: warning: ignoring return value of 'kfifo_out', declared with attribute warn_unused_result ... This patch fixes the issue by properly checking the return value.
