IntelFrameworkModulePkg: Fix UEFI and Tiano Decompression logic issue

https://bugzilla.tianocore.org/show_bug.cgi?id=1317

This is a regression issue caused by 684db6da64bc7b5faee4e1174e801c245f563b5c.
In Decode() function, once mOutBuf is fully filled, Decode() should return.
Current logic misses the checker of mOutBuf after while() loop.
