Hi Jakub,
this patch fixes a bug in lower_omp_target, where for Fortran arrays,
the expanded sender assignment is wrongly using the variable in the
current ctx, instead of the one looked-up outside, which is causing
use_device_ptr/addr to fail to work when used inside an omp-parallel
(where the omp child_fn is split away from the original).
Just a one-character change to fix this.

The fix is inside omp-low.cc, though because the omp_array_data langhook
is used only by Fortran, this is essentially Fortran-specific.

Tested on x86_64-linux + nvptx offloading without regressions.
This is probably not a regression, but seeking to commit when stage1 opens.

Thanks,
Chung-Lin
