salvaged: Fix "-parallel all<number>" parsing
In salavageserver -parallel option takes "all<number>" argument.
However the code does not parse the numeric part correctly. Due
to this, only single instance of salvageserver process was running
even if we provide the larger number with "all" argument.
With this fix, numeric part of "all" argument will be parsed
correctly and will start required number of salvageserver instances.
