Fix mess with struct tbf types passed to LOGPTBF macro
It is quite common in all osmo-pcu code to have to convert between
parent class "tbf" and children "dl_tbf"/"ul_tbf", or other way around.
This commit adds new helper static inline functions to cast between
those while doing type checks.
This is used by new LOGPTBFDL and LOGPTBFUL macros to now expect the
proper subclass and cast securely inside the macro itself, hence sparing
all code calling those macros to have to cast explicitly the pointer to
the parent "tbf" class.
