dc sweep fails after transient sim: 

keep MODEDCTRANCURVE as provided by commit
7d8236766 ("b3ld.c, b4ld.c, b3v32ld.c: enable capacitance calculation during dc sweep", 2012-10-03)
Instead exclude current integration when MODEDCTRANCURVE is selected.
Unify setting ChargeComputationNeeded in b4vdld.c,
make it as in other b4xxld.c.
