dmaengine: stm32-dma3: Set lli_size after allocation
With the new __counted_by annotation, the "lli_size" variable needs to
valid for accesses to the "lli" array. This requirement is not met in
stm32_dma3_chan_desc_alloc(), since "lli_size" starts at "0", so "lli"
index "0" will not be considered valid during the initialization for loop.
Fix this by setting lli_size immediately after allocation (similar to
how this is handled in stm32_mdma_alloc_desc() for the node/count
relationship).
Fixes: f561ec8b2b33 ("dmaengine: Add STM32 DMA3 support")
