RDMA/core: Fix null-ptr-deref in ib_core_cleanup()
[ Upstream commit 07c0d131cc0fe1f3981a42958fc52d573d303d89 ]
KASAN reported a null-ptr-deref error:
KASAN: null-ptr-deref in range [0x000000000
RDMA/core: Fix null-ptr-deref in ib_core_cleanup()

It is because the fail of roce_gid_mgmt_init() is ignored:
ib_core_init()

gid_cache_wq = alloc_ordered_workqueue # fail
...
ib_core_cleanup()
roce_gid_mgmt_cleanup()
destroy_workqueue(gid_cache_wq)
# destroy an unallocated wq
Fix this by catching the fail of roce_gid_mgmt_init() in ib_core_init().
