network: do not check deprecated flag in address_is_ready()

Without this change, the address with PreferredLifetime=0 cannot be ready,
and thus, no consequent setting up process does not start.
The bug was introduced by 6aa5773.

Follow-up for b7ed5384ab55cd4d7b8d7d1ec7f5d5e145f0a2b1.

Fixes #13341.
