test out xfs_inactive_attrs in log replay for iunlink processing.

Merge of master-melb:xfs-cmds:29701a by kenmcd.

  Update args to use command options for multi_open_unlink.
  Change a sleep to a wait as we were just sleeping to account
  for the death of a process - should really wait for its death.

+# FS QA Test No. 181
+#
+# Like 121 only creating large EAs
+# As part of the iunlink processing in recovery it will call VN_RELE
+# which will inactivate the inodes and if they have EAs (which they
+# will here) also call xfs_inactive_attrs.
+# We want to test out this xfs_inactive_attrs code being called in recovery.
