logging: substitute %w for %v

Subsitute the format specifier %w for %v in the logging facility. The
logging functions use a fmt.Sprintf call behind the scene which does not
recognize %w. %w should be used in fmt.Errorf when you want to wrap
errors. Hence, the log entries that use %w are improperly formatted like
this:

ERROR 2022/10/02 09:13:57.724529 worker.go:439: could not get message
info %!w(*fmt.wrapError=&{could not get structure: [snip] })
      ^
