master a5ce31a192: Use assq_no_quit on all local_var_alist accesses

[Lars Ingebrigtsen]

branch: master
commit a5ce31a192f474bce1259b97e599258d1fde7c8c
Author: Sergey Vinokurov <serg.foo@gmail.com>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Use assq_no_quit on all local_var_alist accesses
    
    * src/data.c (Fkill_local_variable):
    * src/buffer.c (buffer_local_value): Use assq_no_quit instead of
    Fassoc/Fassq on local_var_alist (bug#53242).
    
    * src/data.c (Flocal_variable_p): Use assq_no_quit instead of
    open-coding the search on local_var_alist.
