openmp: Fix up cp/parser.c build with GCC 4.8 to 6

Christophe Lyon reported that cp/parser.c no longer compiles with
GCC 4.8.5 after my recent OpenMP changes.
A goto out; there crosses odsd variable declaration, and odsd has
a vec<...> member where vec has = default; default constructor
and gcc before r7-2822-gd0b0fbd9fce2f30a82558bf2308b3a7b56c2f364
treated that as error.

Fixed by moving the declaration earlier before the goto.

Tested on x86_64-linux with GCC 4.8.5 system gcc, committed to trunk
as obvious.

	* parser.c (cp_parser_member_declaration): Move odsd declaration
	before cp_parser_using_declaration call to avoid errors with
	GCC 4.8 to 6.
