[patch, fortran] DTIO write format stored in a string leads to severe errors

[Jerry DeLisle]

I plan to commit the attached patch which eliminates the offending behavior and
allows the test cases to run.

I opened a new PR to address the remaining issues.

See Bug 83829 - Implement runtime checks for DT format specifier and alignment
with effective item.

Regression tested on x86_64-pc-linux-gnu.

The patch is simple. I will roll in a test case soon.

Regards,

Jerry
