Dev Jain b2b4b46a52 malloc: fix large tcache code to check for exact size match
The tcache is used for allocation only if an exact match is found. In the
large tcache code added in commit cbfd798810, we currently extract a
chunk of size greater than or equal to the size we need, but don't check
strict equality. This patch fixes that behaviour.
