Pointer mode is being assigned a value that is never read, it is
being re-assigned later with a new value. The initialization is
redundant and can be removed.

Cleans up clang scan build warning:
drivers/gpu/drm/solomon/ssd130x.c:582:27: warning: Value stored
to 'mode' during its initialization is never read [deadcode.DeadStores]
