xfs/{529,531,532,534,535} attempt to create test files after injecting
reduce_max_iextents error tag. Creation of test files fails when using a
multi-block directory test configuration because,
1. A directory can have a pseudo maximum extent count of 10.
2. In the worst case a directory entry creation operation can consume
(XFS_DA_NODE_MAXDEPTH + 1 + 1) * (Nr fs blocks in a single directory block)
extents.
With 1k fs block size and 4k directory block size, this evaluates to,
(5 + 1 + 1) * 4
= 7 * 4
= 28
> 10 (Pseudo maximum inode extent count).
This commit fixes the issue by creating test files before injecting
reduce_max_iextents error tag.
