Otherwise this looks odd. It should not be both set to value. Will fix this in th next version.

Fix the following smatch warning: smatch warnings: drivers/net/ethernet/microchip/vcap/vcap_api_debugfs.c:103 vcap_debugfs_show_rule_keyfield() error: uninitialized symbol 'value'. drivers/net/ethernet/microchip/vcap/vcap_api_debugfs.c:106 vcap_debugfs_show_rule_keyfield() error: uninitialized symbol 'mask'. In case the vcap field was VCAP_FIELD_U128 and the key was different than IP6_S/DIP then the value and mask were not initialized, therefore initialize them.
