Subject: [PATCH] cpu.c: Check properly for virCapabilitiesGetNodeInfo() retval

The virCapabilitiesGetNodeInfo() function has the usual return
value semantics for integeres: a negative value means an error,
zero or a positive value means success. However, the function
call done in virCPUProbeHost() doesn't check for the return value
accordingly.
