[ Upstream commit 174e9ce0daf6af791386e96e76e743eb59e8a401 ]
The GuC log snapshot code would complain loudly if there was no GuC log to take a snapshot of or if the snapshot alloc failed. Originally, this code was only called on demand when a user (or developer) explicitly requested a dump of the log. Hence an error message was useful.
However, it is now part of the general devcoredump file and is called for any GPU hang. Most people don't care about GuC logs and GPU hangs do not generally mean a kernel/GuC bug. More importantly, there are valid situations where there is no GuC log, e.g. SRIOV VFs.
So drop the error message.
