xfs: check for dinode realtime flag corruption
Ramon tested XFS with a modified version of fsfuzzer and hit a NULL
pointer dereference in __xfs_get_blocks due to the RT device target
pointer being NULL.
To fix this reject inode with the realtime bit set on a a filesystem
without an RT subvolume during inode read.
