[patch] fixed compilation warning in ex_cmds2.c

[Dominique Pellé]

Hi

Attached patch fixes this compilation warning in vim-7.4.1579:

ex_cmds2.c: In function 'check_due_timer':
ex_cmds2.c:1230:12: warning: 'next_due' may be used uninitialized in
this function [-Wmaybe-uninitialized]
     return next_due;
            ^

Regards
Dominique
