[MIRROR] Fix buckled alert unbuckling not working properly (#2875)

* Fix buckled alert unbuckling not working properly (#82627)

## About The Pull Request

So funny thing, while trying to reproduce a different issue on the
current master, I coincidentally let my local instance start without
reading, latejoined on the shuttle, and I noticed it wasn't letting me
unbuckle as easily.

Looking into this a bit later, it seems as if it's a line #82593
accidentally changed while moving around the
`/mob/living/carbon/resist_buckle()` proc's flow.

https://github.com/tgstation/tgstation/blob/fe26373572e41415ec12e2b0785f0c6dc2567577/code/modules/mob/living/carbon/carbon.dm#L238-L241
While before it was
```dm
/mob/living/carbon/resist_buckle()
	if(HAS_TRAIT(src, TRAIT_RESTRAINED))
		(...)
	else
		buckled.user_unbuckle_mob(src,src)
```
Just changing this to `buckled.user_unbuckle_mob(src, src)` fixes this.
## Why It's Good For The Game
