[PATCH net-next 01/11] tools: ynl-gen: fix enum index in _decode_enum(..)

From: Arkadiusz Kubalewski <arkadiusz.kubalewski@intel.com>

Remove wrong index adjustement, which is leftover from adding
support for sparse enums.
enum.entries_by_val() function shall not subtract the start-value, as
it is indexed with real enum value.

Fixes: c311aaa74ca1 ("tools: ynl: fix enum-as-flags in the generic CLI")
