    selftests/uevent: fix -Wmaybe-uninitialized warning in uevent_filtering
    
      uevent_filtering.c: In function 'trigger_uevent':
      uevent_filtering.c:217:16: warning: 'ret' may be used uninitialized [-Wmaybe-uninitialized]
        217 |         return ret;
            |                ^~~
      uevent_filtering.c:197:17: note: 'ret' was declared here
        197 |         int fd, ret;
            |                 ^~~
    
    Initialize 'ret' to 0 in trigger_uevent(). If 'times' is 0, the for
    loop body is never entered and 'ret' would be returned uninitialized.
