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.
