lib: fdtable: fix reference counting in z_reserve_fd() The new fd entry should be reserved by incrementing its reference count in z_reserve_fd() instead of z_finalize_fd() in order to avoid having the same one being returned in a concurrent call. If for some reason the fd is not finalized after z_reserve_fd() is called, it can be freed via z_free_fd(), which would decrement the reference count.
