lib/mpi: mpi_write_sgl(): fix style issue with lzero decrement
Within the copying loop in mpi_write_sgl(), we have
if (lzeros > 0) {
...
lzeros -= sizeof(alimb);
}
However, at this point, lzeros < sizeof(alimb) holds. Make this fact
explicit by rewriting the above to
if (lzeros) {
...
lzeros = 0;
}
