Christophe Leroy 8540571e01 powerpc/32: Fix again csum_partial_copy_generic() 
Commit 7aef413656 ("powerpc32: rewrite csum_partial_copy_generic()
based on copy_tofrom_user()") introduced a bug when destination address
is odd and len is lower than cacheline size.

In that case the resulting csum value doesn't have to be rotated one
byte because the cache-aligned copy part is skipped so no alignment
is performed.

Fixes: 7aef413656 ("powerpc32: rewrite csum_partial_copy_generic() based on copy_tofrom_user()")
