[PATCH] spi: davinci: Remove unneeded NULL checking for dspi and dspi->bitbang.master

[Axel Lin <axel.lin-8E1dMatC8ynQT0dZR+AlfA@public.gmane.org>]

spi_master_get_devdata() never returns NULL when spi_alloc_master() success,
so remove NULL test for dspi.
We have ensured master is not NULL before assigning it to dspi->bitbang.master.
So also remove NULL test for dspi->bitbang.master.
