input/trace32_ad: silence format errors during input format match

When auto-detection tries to find the input module that can handle a
file, unexpected input format should be considered non-fatal. Only emit
error messages when process_header() got invoked from process_buffer()
after initialization. Emit debug messages in early stages where no input
module context exists yet.
