spi/bfin_spi: respect cs_change even in last transferfor-spi
According to the definition of flag cs_change in spi.h, CS should stay
active in the last transfer of a message until the first transfer of
the next message if it's set. The Blackfin SPI driver was not checking
this before deactivating the CS.
