server: document protocol logger callback function

This fixes a validation error in the documentation which are not fatal.

The idea is the same as in 12ec67a ("server: document listener fields
and a vfunc"), which seems to have missed the reference to the
wl_protocol_logger_func_t from the note in wl_log_func_t.
