x86, AMD: Remove needless CPU family check (for L3 cache info)

Old 32-bit AMD CPUs (all w/o L3 cache) should always return 0
for cpuid_edx(0x80000006).

For unknown reason the 32-bit implementation differed from the
64-bit implementation. See commit 67cddd94799 ("i386: Add L3 cache
support to AMD CPUID4 emulation"). The current check is the
result of the x86 merge.
