Subject: [PATCH -next] dmaengine: sf-pdma: Remove set but not used variable "desc"

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

drivers/dma/sf-pdma/sf-pdma.c: In function 'sf_pdma_donebh_tasklet':
drivers/dma/sf-pdma/sf-pdma.c:287:23: warning: unused variable 'desc' [-Wunused-variable]

After commit 8f6b6d060602 ("dmaengine: sf-pdma: Fix an error that calls callback twice"),
variable 'desc' is never used. Remove it to avoid build warning.
