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.
