[mdns] handle allocation failure in RxMessage::Init() (#12193)

Browse Source 
This commit updates `RxMessage::Init()` to handle failures when
reserving capacity for the questions array. Previously, an allocation
failure would trigger an assertion.

By switching to `SuccessOrExit`, the method can now gracefully handle
the allocation failure by returning an error and dropping the
message. This aligns with the general error handling strategy for
received messages and makes the implementation more robust against
out-of-memory conditions.
