media: sti/bdisp: fix pm_runtime_get_sync() usage count
The pm_runtime_get_sync() internally increments the dev->power.usage_count without decrementing it, even on errors. The bdisp_start_streaming() doesn't take it into account, which would unbalance PM usage counter at bdisp_stop_streaming(). The logic at bdisp_probe() is correct, but the best is to use the same call along the driver. So, replace it by the new pm_runtime_resume_and_get(), introduced by: commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter") in order to properly decrement the usage counter, avoiding a potential PM usage counter leak.
