Keith Busch b963f2345f nios2: fix __wsum type degradation in csum_fold() 
csum_fold() shifts a bitwise __wsum type, which sparse reports as
"restricted __wsum degrades to integer". Sparse only checks the body of
a static inline once something instantiates it, so this went unnoticed
until a recent block layer change added the first csum_fold() caller to
a file built on this architecture.

Force cast to a __u32 for the shift, as the other architectures do.

Fixes: eea9507a69 ("nios2: Library functions")
