[PATCH 3/3] xfs/530: Bail out if either of reflink or rmapbt is enabled

[Chandan Babu R <chandanrlinux@gmail.com>]

_scratch_do_mkfs constructs a mkfs command line by concatenating the values of
1. $mkfs_cmd
2. $MKFS_OPTIONS
3. $extra_mkfs_options

The corresponding mkfs command line fails if $MKFS_OPTIONS enables either
reflink or rmapbt feature. The failure occurs because the test tries to create
a filesystem with realtime device enabled. In such a case, _scratch_do_mkfs()
will construct and invoke an mkfs command line without including the value of
$MKFS_OPTIONS.

To prevent such silent failures, this commit causes the test to exit if it
detects either reflink or rmapbt feature being enabled.
