include/linux/fs.h: fix unsigned enum warning with gcc-4.2
With arm-linux-gcc-4.2, almost every file we build in the kernel ends up
with this warning:
include/linux/fs.h:2648: warning: comparison of unsigned expression < 0 is always false
Later versions don't have this problem, but it's easy enough to work
around.
