Vulkan: Fix xfb buffer redefine to smaller size In 89e11878b275b15735eaf273ababfa6fd43a2e3d, a use-after-free bug was fixed where glBufferData redefined a buffer, leading to a change in storage. This was only tested for the case where the new buffer was larger than the old buffer. When the new buffer is smaller however, another issue remains where the buffer size as cached by the transform feedback object used the old object's size. This is worked around in this change, with a fix for the real issue (that the buffer state is updated after calling into the backend instead of before) coming up.
