[MIRROR] removes the force drop when trying to attack with an unwielded crusher (#27988)

* removes the force drop when trying to attack with an unwielded crusher (#83641)

## About The Pull Request

What it says on the tin. If you're not wielding the crusher, rather than
forcefully dropping everything in your hands, you simply just don't
attack.

## Why It's Good For The Game

This was added when the crusher was able to be held in one-hand, before
we got the two-handed component. However, for some inexplicable reason
there was a noob trap added into that feature that has existed for
almost five years. Maybe skoglol had their reasons for putting it in
there at the time, but I don't believe this is anything other than
unnecessarily punishing in the modern state of the code. A return works
just fine.
