[PATCH] malloc: fix large tcache code to check for exact size match

[Cupertino Miranda]

Hi Dev,

I am certain it might reproduce the error, but it is not reporting when 
it actually assigns a bigger chunk to a smaller allocation.
We should be catching this type of mistakes in testing.
Also it should be an independent test specific to the reported bug.

Cheers,
Cupertino
