dmaengine: sh: Fix unused initialization of pointer lmdesc
Pointer lmdesc is being inintialized with a value that is never read,
it is later being re-assigned a new value. Fix this by initializing
it with the latter value.
Addresses-Coverity: ("Unused value")
Fixes: 550c591a89a1 ("dmaengine: sh: Add DMAC driver for RZ/G2L SoC")
