drm/xe/oa: Call xe_oa_emit_oa_config() with new config when updating config

Browse Source 
When UMD ask config to be updated, xe_oa_config_locked() was calling
xe_oa_emit_oa_config() that would use stream->oa_config but that is
only changed to the next oa_config after xe_oa_emit_oa_config() finish.
So it was setting the same config for all DRM_XE_PERF_IOCTL_CONFIG
calls.
