RDMA/mlx5: Fix ucaps init error flow

Browse source

[ Upstream commit 6dc78c53de ]

In mlx5_ib_stage_caps_init(), if mlx5_ib_init_ucaps() fails after
mlx5_ib_init_var_table() succeeds, the VAR bitmap is leaked since
the function returns without cleanup.

Thus, cleanup the var table bitmap in case of error of initializing
ucaps before exiting, preventing the leak above.
