drivers: net: xgene: Fix dma_unmap_single() size
In xgene_enet_refill_bufpool(), the skb->data is dma-mapped with length
len which is set to XGENE_ENET_STD_MTU which equals 1536. However, in
xgene_enet_delete_bufpool(), the same buffer is unmapped with length
XGENE_ENET_MAX_MTU which is 9600. This may erroneously unmap other
DMA buffers or cause other issues.
Change unmap length to XGENE_ENET_STD_MTU.
Cc: stable+noautosel@kernel.org # LLM report + LLM fix, untested
