Subject: [PATCH] [routing-manager] simplify `PdPrefixManager::HasPrefix()`
 (#11242)

This commit simplifies `PdPrefixManager::HasPrefix()` by simply
checking if `mPrefix` is empty (rather than `IsValidOmrPrefix()`).
A favored PD prefix is always validated before it is assigned to
`mPrefix`, and when the prefix is removed, `mPrefix` is cleared.
