Insert an explicit cast for -Wc++11-narrowing error #181

Building with gcc 11.2.0 or clang 13.0.1
64 bit builds are ok with gcc or clang.
For a 32 bit build, with gcc is ok, but with clang, this failure occurs:

32 bit builds are done in a chroot in the 64 bit host, hence with a 64 bit kernel.
64 bit builds are also done in a chroot.

Patching as proposed in the error message allows the 32 bit build to complete.
The 64 bit build with the patch is ok.

Looks good, thanks.
