Remove unnecessary current user (co-sysop) level/flag checks

As Andre pointed out, these checks perform no function because a user with a level lower than the user being edited cannot enter the related command-key anyway.

This was just effectively dead code that was held-over from ancient SBBS days, seemingly before I learned to effectively use the || operator:
if(!(atoi(str)>useron.level && console&CON_R_INPUT))
