[Pw_forum] use of starting_magnetization value when restarting an lsda cal.

[Stefano de Gironcoli]

It is ok to restart a calculation w/o removing starting_magnetization 
definitions.
The starting magnetization info is used when the starting potential is 
computed from atomic charges. This is usual case when starting from 
scratch.
When you restart a calculation the first potential is read from file and 
the starting_magnetization keywords are not used and make no harm.
