This debugging macro can expand to a lot of code.
Make it a function to reduce code size.

I acked this before; however there is a bug that breaks the build if
CONFIG_RTLWIFI_DEBUG is not defined. The rest of the code calls
_rtl_dbg_trace(), but that symbol is never defined. The problem can be fixed in
debug.c or debug.h.

Confused a bit.  What breaks again?

Nothing breaks and your patch is OK. I had ported it to a GitHub repo of these 
drivers, which had a different debug.h. That led to the missing global when 
CONFIG_RTLWIFI_DEBUG was not defined. That has now been fixed.

Sorry for the confusion.
