x86, microcode, AMD: Extend ucode size verification

Upstream commit: 44d60c0f5c58c2168f31df9a481761451840eb54

The different families have a different max size for the ucode patch,
adjust size checking to the family we're running on. Also, do not
vzalloc the max size of the ucode but only the actual size that is
passed on from the firmware loader.
