lib/mpi: mpi_write_sgl(): purge redundant pointer arithmetic
Within the copying loop in mpi_write_sgl(), we have
if (lzeros) {
...
p -= lzeros;
y = lzeros;
}
p = p - (sizeof(alimb) - y);
If lzeros == 0, then y == 0, too. Thus, lzeros gets subtracted and added
back again to p.
Purge this redundancy.
