[MIRROR] Fixes cigarettes smoking on any slot [MDB IGNORE] (#23907)

* Fixes cigarettes smoking on any slot (#78544)

## About The Pull Request

#76881 allowed you to put cigarettes in a gas mask but removed the check
for, if the thing was a cigarette, making sure it was in your mask slot.

What this meant was that standing around with a cigarette in your hand
would still make you passively smoke it - although this is somewhat more
immersive to me as a former smoker, it also gets obnoxious having to set
the cigarette on a table or put it in my bag to avoid racking up the
ridiculously easy-to-accumulate nicotine addiction points you otherwise
get from even one cigarette in-game.

This just readds that check after the checks for gas masks/non-smoker
locations (which may also be broken but are beyond me right now - trying
to put a cigarette into a gas mask's filter* slot returns 'mask's mouth
is covered.')

* Fixes cigarettes smoking on any slot
