Verbose()<=40 skip checkwrite for zgemm and alloc.
'chi_RegQbz off' and 'EIBZmode off' works.

In GWinput, we can set
--------------
chi_RegQbz off
--------------
Then it use mesh without Gamma for hx0fp0/hx0fp0_sc.
The it automatically set EIBZmode off.

EIBZmode off do not do symmetrization through x0kf_v4h, called from hx0fp0.m.F/hx0fp0.sc.m.F.
This may (or may not) speed up calculations.

Because of intrinsic reason (or because of poor implemenation),
symmetrization is exensive.
