Makes fs getfid error handling consistent with other fs commands

Makes fs getfid error handling consistent with other fs commands

This patch makes the fs getfid command print errors for paths that
can't be handled correctly, instead of quietly ignoring them, and it
also returns an error code if any such paths are encountered.  This
makes the behavior consistent with other fs commands, such as
listquota, whereis, etc.
