[flang] More precise enforcement of runtime constraint

An OPEN statement that affects an already connected unit
without changing its external file is required to have
STATUS="OLD" or default STATUS=.  The code was eliciting
spurious runtime errors in situations where an OPEN statement
pertained to an existing unit number but did not need to have
STATUS="OLD'.
