[PATCH 1/3] kvm tools: Fix powerpc build errors caused by recent changes

[Michael Ellerman <michael@ellerman.id.au>]

Several caused by commit 8074303 "remove global kvm object",
ioport__setup_arch(), term_getc_iov() & term_getc() in the
spapr_hvcons.c code, and kvm_cpu__reboot() in rtas_power_off().

Commit 221b584 "move active_console into struct kvm_config" added
checks in h_put_term_char() & h_get_term_char() of
kvm->cfg.active_console but needs to be vcpu->kvm->cfg.active_console.

That commit also missed updates to term_putc() & term_getc() in
spapr_rtas.c, and I'm guessing that we need similar checks of
active_console in rtas_put_term_char() & rtas_get_term_char().
