QVarLengthArray: remove unneeded copy in replace()

QVarLengthArray is neither implicitly shared, nor does it feature a
magic resize() on out-of-bounds.

Therefore, data() doesn't detach(), so 't' remains stable.

The only reason for the copy, then, would be if T wasn't
self-assignment-safe, but we don't support such types.

Remove the copy.
