Subject: [PATCH 06/14] x86/microcode/intel: Use appropriate type in microcode_sanity_check()

The data type of print_err parameter used by microcode_sanity_check()
is int. In prepration 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.
