crypto: lskcipher - propagate errors from unaligned crypt

The while loop declares a second err variable that shadows the outer
one. When the crypt callback fails, the goto out path returns the outer
err, which still holds the -ENOMEM value assigned before the successful
allocation check. The real error from the cipher is discarded and the
caller sees -ENOMEM instead.

Drop the inner declaration so the callback error reaches the caller.

Verified with a test module that registers an lskcipher whose encrypt
callback fails with -EIO and calls it through a misaligned buffer.
An unpatched kernel returns -ENOMEM, a patched kernel returns -EIO.

Found with Clang's -Wshadow.
