Not quite, all of the RT_PRINT_DATA are emitted at KERN_DEBUG.
These DBG_*s are just a normal debug verbosity level.
It does seem odd though to have a DBG_EMERG and not always
emit it.
What might also be useful for any embedded use is to add
CONFIG_RTLWIFI_DEBUG to conditionally remove all of the
debug logging code to reduce the largish object size.
This reduces the object size by about 1/3 (250KB)
when CONFIG_RTLWIFI_DEBUG is not set.
