soc/intel: Fix microcode loading
Commit 1aa60a95bd8363d2 broke microcode loading for chipsets that have a
microcode blob with a total_size field set to 0. This appears to be
support for older chipsets, where the size was set to 0 and assumed to
be 2048 bytes. The fix is to change the result of the subtraction to a
signed type, and ensure the following comparison is done without
promoting the signed type to an unsigned one.
