spi: davinci: do not treat Tx interrupt being set as error
In davinci_spi_check_error(), Tx interrupt being set is
treated as error. This function is only meant to flag
bus error conditions and Tx interrupt being set at that
point is not a bus error but rather a driver bug.
Stop checking for Tx interrupt and flagging that as an
IO error.
