crypto: scatterwalk - Remove unused inline function scatterwalk_aligned()

The scatterwalk_aligned() are no longer used since removing blkcipher
and ablkcipher support, all use of it has been removed since
commit d63007eb ("crypto: ablkcipher - remove deprecated
and unused ablkcipher support"), so remove it.
