Fix one issue in OpenMP 'requires' directive diagnostics
Fix-up for recent commit 683f11843974f0bdf42f79cdcbb0c2b43c7b81b0
"OpenMP: Move omp requires checks to libgomp".
gcc/
* lto-cgraph.cc (input_offload_tables) <LTO_symtab_edge>: Correct
'fn2' computation.
libgomp/
* testsuite/libgomp.c-c++-common/requires-1.c: Add 'dg-note's.
* testsuite/libgomp.c-c++-common/requires-2.c: Likewise.
* testsuite/libgomp.c-c++-common/requires-3.c: Likewise.
* testsuite/libgomp.c-c++-common/requires-7.c: Likewise.
* testsuite/libgomp.fortran/requires-1.f90: Likewise.
(cherry picked from commit faa0c328ee65f0d6d65d6e20181d26e336071919)
