The XFS_WANT_CORRUPT_* macros conceal subtle side effects such as the
creation of local variables and redirections of the code flow. This is
pretty ugly, so replace them with explicit XFS_IS_CORRUPT tests that
remove both of those ugly points. The change was performed with the
following coccinelle script:
@@
expression mp, test;
identifier label;

- XFS_WANT_CORRUPTED_GOTO(mp, test, label);
