x86: Fix 32-bit *_cpu_data initializers

The commit 27be457000211a6903968dfce06d5f73f051a217
('x86 idle: remove 32-bit-only "no-hlt" parameter, hlt_works_ok
flag') removed the hlt_works_ok flag from struct cpuinfo_x86, but
boot_cpu_data and new_cpu_data initializers were not changed
causing setting f00f_bug flag, instead of fdiv_bug.

If CONFIG_X86_F00F_BUG is not set the f00f_bug flag is never
cleared.

To avoid such problems in future C99-style initialization is now
used.
