[SRU Bionic/Focal] vsock: remove ratelimit unknown ioctl message

[Thadeu Lima de Souza Cascardo]

From: Colin Ian King <colin.king at canonical.com>

BugLink: https://bugs.launchpad.net/bugs/1971480

When exercising the kernel with stress-ng with some ioctl tests the
"Unknown ioctl" error message is spamming the kernel log at a high
rate. Remove this message.
