The pointer last_sg is being assigned a value at the start of a loop
however it is never read and is being re-assigned later on in both
brances of an if-statement. The assignment is redundant and can be
removed.
Cleans up clang scan-build warning:
drivers/dma/fsl-edma-common.c:563:3: warning: Value stored to 'last_sg'
is never read [deadcode.DeadStores]
