QCamera3: Fix jpeg settings for HDR+ requests

Save the capture request settings for pending HDR+ requests and
use the settings to override HDR+ capture results given by HDR+
client. This is necessary for the encoder to get the right jpeg
settings because HDR+ capture results given by HDR+ client belong
to ZSL frames, requested in the past.

Test: camera2hdr with HDR+ enabled
