[PATCH v2 11/14] lib/mpi: mpi_read_raw_from_sgl(): purge redundant clearing of nbits

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.
