Avoid crashing on unaligned pointers from corrupted file systems

On platforms that don't permit unaligned pointer dereferences,
corrupted file systems will as used by the regression test suite can
cause e2fsck and debugfs to crash.  Avoid those crashes caused by
corrupted file systems.  With this commit the full set of regression
test suites will pass on the sparc64 platform.
