Markus Armbruster 51bd458166 qga: Fix qmp_guest_suspend_{disk, ram}() error handling
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second

qmp_guest_suspend_disk() and qmp_guest_suspend_ram() pass @local_err
first to check_suspend_mode(), then to acquire_privilege(), then to
execute_async().  Continuing after errors here can only end in tears.
For instance, we risk tripping error_setv()'s assertion.
