staging: gasket: apex: convert various logs to debug level

Debugging information is improperly logged at non-debug log level in a
number of places, and some logs regarding error conditions may be
generated too frequently, such that these could cause performance
problems and/or obscure other logs.  Convert these to debug log level.
