soc: qcom: pil: Remove null character writing of shared mem 



PIL is writing '\0' in the shared mem region. This
region is shared with other clients that are also trying
to read. Hence they miss first character.

Remove this null character writing by PIL, as this mem
area is supposed to be Read only.
