The functions qat_crypto_get_instance_node() and
qat_compression_get_instance_node() allow to get a QAT instance (ring
pair) on a device close to the node specified as input parameter.
When this is not possible, and a QAT device is available in the system,
these function return an instance on a remote node and they print a
message reporting that it is not possible to find a device on the specified
node. This is interpreted by people as an error rather than an info.
The print "Could not find a device on node" indicates that a kernel
application is running on a core in a socket that does not have a QAT
device directly attached to it and performance might suffer.
Due to the nature of the message, this can be considered as a debug
message, therefore drop the severity to debug and report it only once
to avoid flooding.
