Summary
RDMA/mana: Fix mana_destroy_wq_obj() cleanup in mana_ib_create_qp_rss()
Details

In the Linux kernel, the following vulnerability has been resolved:

RDMA/mana: Fix mana_destroy_wq_obj() cleanup in mana_ib_create_qp_rss()

Sashiko points out there are two bugs here in the error unwind flow, both related to how the WQ table is unwound.

First there is a double i-- on the first failure path due to the while loop having a i--, remove it.

Second if mana_ib_install_cq_cb() fails then mana_create_wq_obj() is not undone due to the above i--.
