hs: Correctly validate v3 descriptor encrypted length

Browse Source 
The encrypted_data_length_is_valid() function wasn't validating correctly the
length of the encrypted data of a v3 descriptor. The side effect of this is
that an HSDir was rejecting the descriptor and ultimately not storing it.

Fixes #22447
