[ Upstream commit 0b698c838e84149b690c7e979f78cccb6f8aa4b9 ]
I stumbled over an old OSA model that claims to support DIAG_ASSIST, but then rejects the cmd to query its DIAG capabilities.
In the old code this was ok, as the returned raw error code was > 0. Now that we translate the raw codes to errnos, the "rc < 0" causes us to fail the initialization of the device.
The fix is trivial: don't bail out when the DIAG query fails. Such an error is not critical, we can still use the device (with a slightly reduced set of features).
