Add a couple of tests to check that we don't leak inodes or dquots
if CoW recovery fails and therefore the mount fails.

+# Ensure that we don't leak quota inodes when CoW recovery fails.
+#
+# Use xfs_fsr to inject bmap redo items in the log for a linked file and
+# an unlinked file; enable quota so that we always mount with the quota
+# inodes; and then corrupt the refcount btree to ensure that the CoW
+# garbage collection (and therefore the mount) fail.
+#
+# On a subsequent mount attempt, we should be able to replay the bmap
+# items for the linked and unlinked files without prematurely truncating
+# the unlinked inode and without leaking the linked inode, and we should
+# be able to release the quota inodes when we're aborting the mount. We
+# also should not leak dquots.
