In iwl_mvm_add_sta() we're initializing the new allocated mvm_sta.
We are setting some fields to zero even though it was allocated with
kzalloc, for the case of HW restart. But in such a case we will never
get to this initializations due to the goto statement that we have in
this case. Remove these initializations.
