x86: ivybridge: remove unused uma_memory_size
The value of uma_memory_size depends on an undefined value from the stack. The value of uma_memory_size is changed but never used. So simply remove this superfluous code. The problem was indicated by cppcheck. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
