qapi: Fix argument description indentation stripping
When an argument's description starts on the line after the "#arg: "
line, indentation is stripped only from the description's first line,
as demonstrated by the previous commit. Moreover, subsequent lines
with less indentation are not rejected.
Make the first line's indentation the expected indentation for the
remainder of the description. This fixes indentation stripping, and
also requires at least that much indentation.
