apply_mask in HuBERT does not apply expected percentage of masks if the input shapes differ. which is true in the case of fintuning. #5642

mask_indices = compute_mask_indices(
(B, T),
padding_mask,
self.mask_prob,
self.mask_length,
self.mask_selection,
self.mask_other,
min_masks=2,

)
require_same_masks need to set to False, which is not the case default.
