fd: FS_IOC_SETFLAGS takes an int* argument not a long*

Browse Source 
According to ioctl_iflags(2):

	The type of the argument given to the FS_IOC_GETFLAGS and
	FS_IOC_SETFLAGS  operations is int *, notwithstanding the
	implication in the kernel source file include/uapi/linux/fs.h
	that the argument is long *.

So this code doesn't work on be64 machines.

Also, Valgrind complains about it.
