[PATCH v3 10/12] media: staging: rkisp1: params: no need to lock default config

[Dafna Hirschfeld <dafna.hirschfeld@xxxxxxxxxxxxx>]

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.
