Ignore IO error if /var/db mounted readonly

:Release Notes:
Ignore IO error when determine 'db not open' if /var/db readonly

:Detailed Notes:
During shutdown process, whole partition will be remounted as
readonly one. In this case, DB will not be opened hence it might
call 'doUserDefault'. This patch is to avoid this situation.

:Testing Performed:
Checks whether it avoids the case.

:QA Notes:

:Issues Addressed:
[ANG-6181] Power off just after power-on, then try user default
[BHV-11779] Forward-port acadiadvb items into beehive
