s3:vfs_gpfs: Use directory not file to get fileset id
The query of the fileset quota needs to determine the file set id first.
With the currently available interface, this requires opening the file
to get a file descriptor. For files, this open can fail when a share
mode is set.
Workaround this by querying the fileset id on the directory instead.
The proper solution would be getting an interface for getting the
fileset id that does not require opening the file.
