[PATCH net V2 01/11] net/mlx5: HWS, Fix memory leak in hws_pool_buddy_init error path

[Mark Bloch <mbloch@nvidia.com>]

From: Lama Kayal <lkayal@nvidia.com>

In the error path of hws_pool_buddy_init(), the buddy allocator cleanup
doesn't free the allocator structure itself, causing a memory leak.

Add the missing kfree() to properly release all allocated memory.

Fixes: c61afff94373 ("net/mlx5: HWS, added memory management handling")
