Fix crash (segfault) in etags on generating tags for Erlang files
* lib-src/etags.c: Set allocated and lastlen to zero, after
freeing last ptr in Erlang_functions to prevent dereferencing NULL
pointer (bug#45122).
Copyright-paperwork-exempt: yes
(cherry picked from commit 2d8f0364fcd1d5dad2b82dd3a9af870b03854547)
