Subject: [PATCH 2/3] st.ko: remove unnecessary normalize_buffer

This patch removes an unnecessary call to normalize_buffer() in enlarge_buffer()

In st_open() always a buffer of one page is allocated. When the buffer needs to be enlarged later, it does not make sense to free this page unconditionally.
