Revert "prealloc room for some number of Elements to avoid malloc"

This reverts commit 94cbbba96f1a2a425663e631c09591023f2e48d7.

Reason for revert: exceeded stack-size on g3 (in SkPDFDevice.cpp:1552

Original change's description:
> prealloc room for some number of Elements to avoid malloc
> 
> I chose 16, as in my test case from android, the depth was
> at least 9. Possibly we could make it even smaller if our
> underlying impl (SkDeque) would never prune its allocations,
> so that we don't malloc repeatedly if we save/restore/save/restore
> across the boundary of the first/nth chunk...
