nssdb: Fix parsing multiple parameters

Previously, the parsing of multiple parameters did not continue
from the previous offset, but reverted back to the start of the
string when we went through multiple parameters.

The follow-up parameters also had a leading space separator
character, which prevented matching it against the defined names.
