logging: Reduce device discovering verbosity

[zeeke]

The DiscoverSriovDevices routine produces a huge amount of log entries, making debugging problems hard.

Remove log entries that can produce a log line for each configured VF and which does not produce any change in the environment.

The following data comes from a lab I debugged recently:

Analysing a 51 Megabytes rotated log file:

$ ls -lh config-daemon.log
-rw-r--r--. 1 apanatto apanatto 51M Oct 18 12:26 config-daemon.log

$ wc -l config-daemon.log
267148 config-daemon.log

for 2h32m of idle application

$ tail -n 1 config-daemon.log
2024-09-23T12:40:30.620250456Z     INFO    daemon/writer.go:147    setNodeStateStatus(): status    {"sync-status": "Succeeded", "last-sync-error": ""}

$ head -n 1 config-daemon.log
2024-09-23T10:08:47.308287975Z     LEVEL(-2)       daemon/daemon.go:220    get item from queue     {"item": 2}

$ grep "DiscoverVDPAType() discover device type" config-daemon.log | wc -l
84736

$ grep "DiscoverVDPAType(): VDPA device for VF not found" config-daemon.log | wc -l
84736

grep "sriov/sriov.go:127     TryGetInterfaceName()" config-daemon.log | wc -l
84736

Which is 95% of the whole file.
