drm/vc4: remove redundant assignment of variable size

The variable 'size' is being assigned a value that is never read,
the assignment is redundant and can be removed. Cleans up clang-scan
warning:

drivers/gpu/drm/vc4/vc4_bo.c:358:2: warning: Value stored to 'size'
is never read [deadcode.DeadStores]
        size = roundup(size, PAGE_SIZE);
