media: go7007: avoid clang frame overflow warning with KASAN
clang-8 warns about one function here when KASAN is enabled, even without the 'asan-stack' option: drivers/media/usb/go7007/go7007-fw.c:1551:5: warning: stack frame size of 2656 bytes in function I have reported this issue in the llvm bugzilla, but to make it work with the clang-8 release, a small annotation is still needed.
