[src/{mul.c,sqr.c}] Minor changes, making code similar to sub1sp.c.

Checked with
  grep -A 1 'sb *>>' src/*.c
that the bug fixed in r11974 does not occur in other parts of the code.
BTW, there is much duplicate code, as shown by the grep output, and
using macros could have avoided that, making bugs easier to reproduce
(since a same bug would be duplicate several times).
