[U-Boot] [PATCH] zynq: spi: Remove unnecessary error condition

[Michal Simek]

From: Siva Durga Prasad Paladugu <siva.durga.paladugu at xilinx.com>

Removed the unnecessary error check from spi_xfer
as the bitlen zero is possible now to deassert the
chip select for which no data is required to be transfered.
