Yuli Wang 9f15a8df54 LoongArch: csum: Fix OoB access in IP checksum code for negative lengths 
[ Upstream commit 6287f1a8c1 ]

Commit 69e3a6aa6b ("LoongArch: Add checksum optimization for 64-bit
system") would cause an undefined shift and an out-of-bounds read.

Commit 8bd795fedb ("arm64: csum: Fix OoB access in IP checksum code
for negative lengths") fixes the same issue on ARM64.

Fixes: 69e3a6aa6b ("LoongArch: Add checksum optimization for 64-bit system")
