dmaengine: iop-adma: remove set but not used variable 'slots_per_op'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/dma/iop-adma.c: In function iop_adma_tx_submit:
drivers/dma/iop-adma.c:367:6: warning:
 variable slots_per_op set but not used [-Wunused-but-set-variable]

It is never used, so can be removed.
