[PULL v2 38/45] hw/riscv/virt.c: fix non-KVM --enable-debug build |

From: Daniel Henrique Barboza <dbarboza@ventanamicro.com>
A build with --enable-debug and without KVM will fail as follows:
/usr/bin/ld: libqemu-riscv64-softmmu.fa.p/hw_riscv_virt.c.o: in function
`virt_machine_init':
./qemu/build/../hw/riscv/virt.c:1465: undefined reference to
`kvm_riscv_aia_create'
This happens because the code block with "if virt_use_kvm_aia(s)" isn't
being ignored by the debug build, resulting in an undefined reference to
a KVM only function.
Add a 'kvm_enabled()' conditional together with virt_use_kvm_aia() will
make the compiler crop the kvm_riscv_aia_create() call entirely from a
non-KVM build. Note that adding the 'kvm_enabled()' conditional inside
virt_use_kvm_aia() won't fix the build because this function would need
to be inlined multiple times to make the compiler zero out the entire
block.
While we're at it, use kvm_enabled() in all instances where
virt_use_kvm_aia() is checked to allow the compiler to elide these other
kvm-only instances as well.
