[PATCH] useful: Remove extra semicolons after DEFINE_CLEANUP_FUNC()

The DEFINE_CLEANUP_FUNC() macro substitutes an inline function
definition that ends with a '}'. All the users of the macro add a
semicolon after the macro, so to the C compiler it ends up looking like
there's an extra semicolon after the inline function.

When non-ELL source files include ELL headers and use '-pedantic' with
gcc, the compiler complains:

error: ISO C does not allow extra ‘;’ outside of a function [-Werror=pedantic]

The non-ELL files can work around this with pragmas, but it does make
sense for ELL headers to be compliant with the C standard.
