spi: omap2-mcspi: Fix the redifine warning

Browse Source 
Fix the below warning
drivers/spi/spi-omap2-mcspi.c:336:34: warning: symbol 'tx' shadows an earlier one
drivers/spi/spi-omap2-mcspi.c:327:12: originally declared here

So delete the u8 tx as it is assigned and not used(resigned afterwards).
