[PATCH] spi: Do not print a message if spi_controller_{suspend,resume}() fails

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

spi_controller_{suspend,resume}() already prints an error message on
failure, so there is no need to repeat this in individual drivers.

Note: spi_master_{suspend,resume}() is an alias for
      spi_controller_{suspend,resume}().
