Martin Buck 59ee9d2a79 lib: Handle call to zlog_5424_cycle() without valid FD properly 
In zlog_5424_cycle(), struct zlt_5424 *zlt only points to valid memory when
the passed file descriptor is >= 0 (and passing -1 seems to be a supported
use case). So we shouldn't try to compute the address of its zt member when
zlt is NULL.
