Don’t use garbage after tty_frame_at returns nil

Browse source 
* src/term.c (handle_one_term_event): Don’t access possibly
uninitialized storage if frame is nil.  This fixes an issue introduced
in commit 5eae7f5227 dated 2025-01-26
14:43:51 -0800. Issue caught by --enable-gcc-warnings, which enables
-Wanalyzer-use-of-uninitialized-value with gcc (GCC) 14.2.1 20250110
(Red Hat 14.2.1-7).
