[net 03/11] net/mlx5: DR, Fix wrong allocation of modify hdr pattern

[Saeed Mahameed <saeed@kernel.org>]

From: Yevgeny Kliteynik <kliteyn@nvidia.com>

Fixing wrong calculation of the modify hdr pattern size,
where the previously calculated number would not be enough
to accommodate the required number of actions.

Fixes: da5d0027d666 ("net/mlx5: DR, Add cache for modify header pattern")
