bgpd: Fix crash when deleting the SRv6 locator
When BGP receives a `SRV6_LOCATOR_DEL` from zebra, it invokes
`bgp_zebra_process_srv6_locator_delete` to process the message.
`bgp_zebra_process_srv6_locator_delete` obtains a pointer to the default
BGP instance and then dereferences this pointer.
If the default BGP instance is not ready / not configured yet, this
pointer this pointer is `NULL` and dereferencing it causes BGP to crash.
This commit fix the issue by adding a a check to verify if the pointer
is `NULL` and returning early if it is.
