zebra: Remove dead SRv6 code
At line 1736, `alloc_mode` is set to `SRV6_SID_ALLOC_MODE_EXPLICIT` or
`SRV6_SID_ALLOC_MODE_DYNAMIC` depending on the `sid_value` variable.
There will never be a case where alloc_mode will be `SRV6_SID_ALLOC_MODE_MAX`
or `SRV6_SID_ALLOC_MODE_UNSPEC`.
Let's replace the `switch(alloc_mode) {...}` with an if-else.
Fixes CID 1594015.
