[flang] Fix INQUIRE of access and formatting possibilities

Authored by klausler on Oct 1 2020, 9:45 AM.



Don't give false positives from INQUIRE about possible
access mode changes on connected units. DIRECT and SEQUENTIAL
cannot be intermixed, apart from allowing DIRECT on a SEQUENTIAL
file with fixed-size records and positioning. Nor can
FORMATTED and UNFORMATTED be interchanged. On unconnected
files, the best that we can do is "UNKNOWN".
