net/mlx5: HWS, Fix uninitialized variables in mlx5hws_pat_calc_nop error flow

[ Upstream commit 24b6e53140475b56cadcccd4e82a93aa5bacf1eb ]

In mlx5hws_pat_calc_nop(), src_field and dst_field are passed to
hws_action_modify_get_target_fields() which should set their values.
However, if an invalid action type is encountered, these variables
remain uninitialized and are later used to update prev_src_field
and prev_dst_field.

Initialize both variables to INVALID_FIELD to ensure they have
defined values in all code paths.
