vsock/vmci: log once the failed queue pair allocation
VMCI feature is not supported in conjunction with the vSphere Fault Tolerance (FT) feature. VMware Tools can repeatedly try to create a vsock connection. If FT is enabled the kernel logs is flooded with the following messages: qp_alloc_hypercall result = -20 Could not attach to queue pair with -20 "qp_alloc_hypercall result = -20" was hidden by commit e8266c4c3307 ("VMCI: Stop log spew when qp allocation isn't possible"), but "Could not attach to queue pair with -20" is still there flooding the log. Since the error message can be useful in some cases, print it only once.
