[spi_device] Latch flip event only when active

Problem:

    `flip` occurs regardless of the buffer's active state. Buffer is
    active only when the read command sends output to the host system.
    `flip` sees the address being latched while address is shifted in to
    the register. It causes premature flip event, which in turn results
    in the incorrect watermark event.

Revised the `flip` logic to latch only when the read buffer manager is
active.
