romio: Update ADIOI_R_Exchange_data function

Squash compiler warning due to whitespace/brace problems.

The code block from lines 829-839 was improperly indented, which led to
both the code being confusing and a compiler warning. Comparing this code to
the current version in the MPICH repo made it clear that the code was simply
improperly indented. Fixing the indentation both makes the code readable and
squashes the compiler warning.
