HAL. This makes it more consistent. This also allows for writing more
comprehensive unit tests for nvgpu.common.init.

CTS test dEQP-VK.api.object_management.max_concurrent.device_group
crashes with invalid userspace memory access.
Currently, nvgpu_submit_prepare_syncs() races with
nvgpu_channel_clean_up_jobs() and this race condition is exposed when
aggressive_sync_destroy_thresh is set to non-zero value.
nvgpu_submit_prepare_syncs() gets ref for c->sync to submit job and
releases channel sync_lock. Meanwhile, nvgpu_worker_poll_work()
triggers nvgpu_channel_clean_up_jobs(), which destroys ref'd c->sync
pointer.
This patch protects channel's sync pointer by holding channel sync_lock
during complete execution of nvgpu_submit_prepare_syncs().
