hso: Use a more common logging style
Macros that end in an underscore are just odd. Add hso_dbg(level, fmt, ...) and use it everwhere instead. Several uses had additional unnecessary newlines as the macro added a newline. Remove the newline from the macro and add newlines to each use as appropriate. Remove now unused D<digit> macros. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.
