Fix nds_beginauth2 on Fedora

nds_beginauth2 was aliging pointer to be multiple of 4 bytes, instead of
aligning offset from start of buffer to the pointer to be multiple of 4
bytes.  This was not problem before, as buffer itself was 4 byte aligned,
but Fedora's compiler has options which can misalign it...

See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=186683.
