[ Upstream commit e16edc99d658cd41c60a44cc14d170697aa3271f ]
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.
