[committed][OG14] openmp: Fix error reporting in parsing of C++ OpenMP to/from clause

[Andrew Stubbs]

From: Kwok Cheung Yeung <kcye...@baylibre.com>

The final 'else' when checking the motion modifiers is nested one level
too deep.

This patch should be folded into "OpenMP: Enable 'declare mapper' mappers for
'target update' directives" when merging to mainline.

gcc/cp/ChangeLog:

        * parser.cc (cp_parser_omp_clause_from_to): Move an "else" clause to
        a higher nesting level.
