KVM: VMX: restore vmx_vmexit alignment
Commit 8bd200d23ec4 ("KVM: VMX: Flatten __vmx_vcpu_run()") changed
vmx_vmexit from SYM_FUNC_START to SYM_INNER_LABEL, accidentally
removing 16 byte alignment as SYM_FUNC_START uses SYM_A_ALIGN and
SYM_INNER_LABEL does not. Josh mentioned [1] this was unintentional.
Fix by changing to SYM_INNER_LABEL_ALIGN instead.
