c-family/c-pretty-print.c - fix for 'restrict' quliafiers

[Gary Funck]

While reviewing some code, I noticed that the logic for
pretty-printing 'restrict' qualifiers is likely missing a
statement that sets 'previous'.

OK to commit?

        * c-pretty-print.c (pp_c_cv_qualifiers):
        Set 'previous' for restrict qualifiers.
