xfs: don't propagate RTINHERIT -> REALTIME when there is no rtdevrealtime-bugs_2020-09-14
While running generic/042 with -drtinherit=1 set in MKFS_OPTIONS, I
observed that the kernel will gladly set the realtime flag on any file
created on the loopback filesystem even though that filesystem doesn't
actually have a realtime device attached. This leads to verifier
failures and doesn't make any sense, so be smarter about this.
