x86/microcode/AMD: Fix a -Wsometimes-uninitialized clang false positive
Initialize equiv_id in order to shut up:
arch/x86/kernel/cpu/microcode/amd.c:714:6: warning: variable 'equiv_id' is \
used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
if (x86_family(bsp_cpuid_1_eax) < 0x17) {
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
because clang doesn't do interprocedural analysis for warnings to see
that this variable won't be used uninitialized.
Fixes: 94838d230a
