Summary
RDMA/cm: Fix leaking the multicast GID table reference
Details

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

RDMA/cm: Fix leaking the multicast GID table reference

If the CM ID is destroyed while the CM event for multicast creating is still queued the cancelworksync() will prevent the work from running which also prevents destroying the ah_attr. This leaks a refcount and triggers a WARN:

GID entry ref leak for dev syz1 index 2 ref=573 WARNING: CPU: 1 PID: 655 at drivers/infiniband/core/cache.c:809 releasegidtable drivers/infiniband/core/cache.c:806 [inline] WARNING: CPU: 1 PID: 655 at drivers/infiniband/core/cache.c:809 gidtablerelease_one+0x284/0x3cc drivers/infiniband/core/cache.c:886

Destroy the ah_attr after canceling the work, it is safe to call this twice.
