net/mlx5: HWS, Fix pattern destruction in mlx5hws_pat_get_pattern error path
[ Upstream commit 00a50e4e8974cbf5d6a1dc91cfa5cce4aa7af05a ]
In mlx5hws_pat_get_pattern(), when mlx5hws_pat_add_pattern_to_cache()
fails, the function attempts to clean up the pattern created by
mlx5hws_cmd_header_modify_pattern_create(). However, it incorrectly
uses *pattern_id which hasn't been set yet, instead of the local
ptrn_id variable that contains the actual pattern ID.
This results in attempting to destroy a pattern using uninitialized
data from the output parameter, rather than the valid pattern ID
returned by the firmware.
Use ptrn_id instead of *pattern_id in the cleanup path to properly
destroy the created pattern.
Fixes: aefc15a0fa1c ("net/mlx5: HWS, added modify header pattern and args handling")
