ovsdb-doc: Fix definition of .TQ macro.

.TP's argument is an optional indentation width, not a string.  The string
goes on the next line.

vswitch.xml didn't actually cause .TQ to be used before, so this wasn't a
problem, but an upcoming commit does add a use, so this commit fixes the
problem in advance.
