spi: Remove note about transfer limit for spi_write_then_read()
Originally spi_write_then_read() used a fixed statically allocated
buffer which limited the maximum message size it could handle. This
restriction was removed a while ago so that we could dynamically
allocate a buffer if required but the kerneldoc was not updated to
reflect this, do so.
