svga: call u_default_redefine_user_buffer() to fix failed assertion

This fixes a regression from a8cf4b6acf9ee996090cc0bb95fa3558b481108c

The problem occured when two successive glDrawArrays calls accessed
subsequent elements in user-space arrays.  The user-space array
from the first call wasn't being grown to accomodate the second
draw call's elements.
