btrfs-progs: check/original: Remove unused variable first_key 

This @first_key variable is introduced in f5c4c4f3b7
("btrfsck: add code to rebuild extent records"), however it's not only
unused, but also used incorrectly.

It's calling btrfs_item_key_to_cpu() on an node extent buffer.

Anyway, just remove it.

Fixes: f5c4c4f3b7 ("btrfsck: add code to rebuild extent records")
