[Stable-7.2.10 27/33] i386/cpuid: Move leaf 7 to correct group

[Michael Tokarev]

From: Xiaoyao Li <xiaoyao.li@intel.com>

CPUID leaf 7 was grouped together with SGX leaf 0x12 by commit
b9edbadefb9e ("i386: Propagate SGX CPUID sub-leafs to KVM") by mistake.

SGX leaf 0x12 has its specific logic to check if subleaf (starting from 2)
is valid or not by checking the bit 0:3 of corresponding EAX is 1 or
not.

Leaf 7 follows the logic that EAX of subleaf 0 enumerates the maximum
valid subleaf.
