Fixes a compile warning [-Wunused-but-set-variable] only.

This fixes the compile time warning:
drivers/mtd/nand/sh_flctl.c: In function 'flctl_dma_fifo0_transfer':
drivers/mtd/nand/sh_flctl.c:354:15: warning: variable 'cookie' set but not
used [-Wunused-but-set-variable]
as dmaengine_submit only reads and returns desc->tx_submit(desc) which
is then unused in flctl_dma_fifo0_transfer, this should be side-effect
free to remove.
Patch was compile tested with ap325rxa_defconfig (implies
CONFIG_MTD_NAND_SH_FLCTL=y)
Patch is against 4.1-rc1 (localversion-next is -next-20150501)
