[PATCH] fstests: Do not execute xfs/{532,533,538} when realtime feature is enabled

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

The minimum length space allocator (i.e. xfs_bmap_exact_minlen_extent_alloc())
depends on the underlying filesystem to be fragmented so that there are enough
one block sized extents available to satify space allocation requests.

xfs/{532,533,538} tests issue space allocation requests for metadata (e.g. for
blocks holding directory and xattr information). With realtime filesystem
instances, these tests would end up fragmenting the space on realtime
device. Hence minimum length space allocator fails since the regular
filesystem space is not fragmented and hence there are no one block sized
extents available.

Thus, this commit disables execution of xfs/{532,533,538} when realtime
feature is enabled on the filesystem instance.
