IB/mlx5: Fix error handling in UVERBS_HANDLER

Currently, if uverbs_attr_ptr_get_array_size() fails, the returned error turns into a huge value, once it is being store into a variable of type size_t (unsigned long), hence never actually reporting such error and causing unexpected behavior when executing function mlx5_ib_create_modify_header().

Fix this by changing the type of variable num_actions from size_t to int.

Fixes cbfdd442c43e ("IB/uverbs: Add helper to get array size from ptr attribute")
