Armando 0c3653b1fd spi_master: fix master HD mode cannot correctly receive data issue when using DMA. ...

Issue Description:
If master is in HD mode, if it sends data without receiving data, it will
still enable the RX DMA because of old version ESP32 silicon issue. And
because there is no correctly linked RX DMA descriptor, an
``inlink_dscr_error`` intr will be seen, which will influence the
following RX transactions.

Solution:
Trigge this workaround only in FD mode.

TODO:
Add a test to check if this workaround related issue does exit. If so,
reporting to Digital Team is also needed.
