mali_kbase: reset: Flush SSCD worker before resetting the GPU
coredump_work isn't guaranteed to happen before reset, which means the
resulting SSCD can contain either of pre-reset or post-reset state.
post-reset state isn't helpful in debugging a GPU hang. Ensure that we
always collect the pre-reset state by flushing the coredump worker
before resetting the GPU.
Bug: 264595878
Test: Raced reset debugfs write with trigger_core_dump sysfs write to
check that the device is stable and coredump happens before reset.
