Use RETURN_PTR(NULL) instead of RETURN_VOID in newNonMovableArray.

RETURN_VOID doesn't set the return value. This means that we are
returning random garbage when the allocation doesn't succeed.

Dalvik :Increase the upper limit check for DexOpt Deps table

Increasing upper limit check for the Deps table as additonal
jars added causes the dalvik to crash while performing dexopt
on cached jar files. This is needed for passing cts test case
which is part of libcore.java.util.jar.DalvikExecTest class
