[PATCH v16 12/21] powerpc: Use sizeof(struct thread_info) in INIT_SP_LIMIT

[Michael Ellerman]

From: Christophe Leroy <christophe.leroy at c-s.fr>

Currently INIT_SP_LIMIT uses sizeof(init_thread_info), but that symbol
won't exist when we enable THREAD_INFO_IN_TASK. So just use the sizeof
the type which is the same value but will continue to work.
