x86, doc only: Correct real-mode kernel header offset for init_size

The real-mode kernel header init_size field is located at 0x260 per the field
listing in th e"REAL-MODE KERNEL HEADER" section. It is listed as 0x25c in
the "DETAILS OF HEADER FIELDS" section, which overlaps with pref_address.
Correct the details listing to 0x260.
