shdma_tx_submit() called via dmaengine_submit() returns the assigned
cookie but this is not used here so the variable and assignment can
be dropped.

V2: As pointed out by Laurent Pinchart <laurent.pinch...@ideasonboard.com>
the variable and assignment can be dropped but not the call to
dmaengine_submit(desc) - fixed up
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)
