net: microchip: vcap: Fix initialization of value and mask 

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.
