lib/mpi: mpi_read_raw_from_sgl(): purge redundant clearing of nbits

Browse Source 
In mpi_read_raw_from_sgl(), unsigned nbits is calculated as follows:

  nbits = nbytes * 8;

and redundantly cleared later on if nbytes == 0:

  if (nbytes > 0)
    ...
  else
    nbits = 0;

Purge this redundant clearing for the sake of clarity.
