Subject: [PATCH 5.11 357/775] IB/mlx5: Add mutex destroy call to cap_mask_mutex mutex

From: Parav Pandit <parav@...dia.com>

[ Upstream commit ab40530a2e0a7aca9a5187824c4fb072f3916e85 ]

mutex_destroy() call for device's cap_mask_mutex mutex is missing, let's
add it to annotate destruction.

Fixes: e126ba97dba9 ("mlx5: Add driver for Mellanox Connect-IB adapters")
