dmaengine: xilinx_dma: remove set but not used variable 'tail_segment'
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/dma/xilinx/xilinx_dma.c: In function 'xilinx_vdma_start_transfer':
drivers/dma/xilinx/xilinx_dma.c:1104:33: warning:
variable 'tail_segment' set but not used [-Wunused-but-set-variable]
It not used since commit b8349172b400 ("dmaengine: xilinx_dma: Drop SG support
for VDMA IP")
