x86/microcode/intel: Use appropriate type in microcode_sanity_check()

The data type of the @print_err parameter used by microcode_sanity_check()
is int. In preparation for exporting this function to be used by
the IFS driver convert it to a more appropriate bool type for readability.

No functional change intended.
