[PATCH v2 14/14] media: staging: rkisp1: params: no need to lock default config

In the function 'rkisp1_params_config_parameter' the lock
is taken while applying the default config. But the lock
only needs to protect the buffers list and the 'is_streaming'
field, so move the locking to lock only what is needed.
