Subject: ftrace: remove packed attribute on ftrace_page.

It causes unaligned access traps on platforms like sparc
(ftrace_page may be marked packed, but once we return
a dyn_ftrace sub-object from this array to another piece
of code, the "packed" part of the typing information doesn't
propagate).

But also, it didn't serve any purpose either.  Even if packed,
on 64-bit or 32-bit, it didn't give us any more dyn_ftrace
entries per-page.
