kvm: assume that many ioeventfds can be created
NR_IOBUS_DEVS was increased to 200 in Linux 2.6.34. By Linux 3.5 it had increased to 1000 and later ioeventfds were changed to not count against the limit. But the earlier limit of 200 would already be enough for kvm_check_many_ioeventfds() to be true, so remove the check. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
