Fix expected BLKGETSIZE64 ioctl result type to 64 bit
The BLKGETSIZE64 ioctl writes 64 bit to the destination address.
In the current implementation the destination pointer is set as u_long,
that is only fine for 64 bit architectures. In 32 bit architectures
u_long is a 32 bit unsigned and might cause the kernel to overwrite
neighbor elements in the stack, leading to unexpected results.
Fix by forcing the destination variable type to 64 bit.
