mke2fs: use ext2fs_get_device_size2() on all platforms
Since commit
e8c858047be6 ("libext2fs: fix build issue for on
Windows/Cygwin systems"), ext2fs_get_device_size2() is available in
Windows builds of libext2fs. So there is no need for mke2fs to call
ext2fs_get_device_size() instead.
This fixes a -Wincompatible-pointer-types warning because
ext2fs_get_device_size() was being passed a 'blk64_t *', but it expected
a 'blk_t *'.
