ice: Fix ice_cfg_rdma_fltr() to only update relevant fields
[ Upstream commit d94dbdc4e0209b5e7d736ab696f8d635b034e3ee ]
The current implementation causes ice_vsi_update() to update all VSI
fields based on the cached VSI context. This also assumes that the
ICE_AQ_VSI_PROP_Q_OPT_VALID bit is set. This can cause problems if the
VSI context is not correctly synced by the driver. Fix this by only
updating the fields that correspond to ICE_AQ_VSI_PROP_Q_OPT_VALID.
Also, make sure to save the updated result in the cached VSI context
on success.
