[fix] DynamicBuffer position error when expand for the firtst time

[Carkham]

Description

When the DynamicBuffer exapnd for the first time, its FloatBuffer.position would incorrectly increase by 1 resulting in an error in the location of subsequent data.

details
This can reproduce the error

DynamicBuffer bb = new DynamicBuffer();
for (int i = 0; i < 129; i++) {
    bb.put((float) i);
}
FloatBuffer buf = bb.getBuffer();
float value = buf.get(128); // This value should be 128f but got 0f.

This problem arises because DynamicBuffer expands when it is about to be full but not yet full, and adds the content before the expansion to the expanded Buffer, but because it is not yet full, the last position before the expansion of the element is not filled, and it is also added to the new Buffer, resulting in the position error of subsequent elements
