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.
