When compiling in x86_32|Debug mode and choosing not to link with standard

Windows libraries, the MSVC compiler will throw the error:
gnu-efi.lib(print.obj) : error LNK2019: unresolved external symbol __allmul referenced in function _ValueToHex

Adding an explicit cast on the array index, to ensure that is not larger
than 32 bits, appears to fix the problem.

NB: This patch also removes trailing whitespaces, but the only real change
is on line 1253.
