[PATCH 03/22] qapi/source: Remove line number from QAPISourceInfo initializer

[John Snow]

With the QAPISourceInfo(None, None, None) construct gone, there's not
really any reason to have to specify that a file starts on the first
line.

Remove it from the initializer and have it default to 1.

Remove the last vestiges where we check for 'line' being unset. That
won't happen again, now!
