The final boss wasnt being that evil even. Yeah keeping someone asleep is shitty but theres an entire island of life at stake in his dream at this point. Also how does Link get home on his two logs and a barrel raft thingy? No food, no drinking water. Middle of nowhere. He dead.
Is this the same Link who uses musical instruments to warp back to places he's already visited? I think he'll be fine.
Link gets rid of his items between games anyways. Since the wind fish world is a dream the ocarina from that world he uses to fast travel here is probably gone too.
There's usually a reason Link doesn't have his items between games, though. For example if it's a different Link (e.g. Wind Waker) or he goes back in time and his Ocarina gets stolen (like in Majora's Mask, where you'll notice he still has his Kokiri Sword to start). If he's stranded and he still has his stuff, I doubt he's going to be tossing it just because lol video game logic.
Only thats exactly what happened. Link isnt loaded with LTTP gear in either Links Awakening or the Oracle games. This iteration of Link has to get 4 boomerangs, one for each adventure, as an example. ---
