IB/core: Fix ib_cache_setup_one error flow cleanup

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

IB/core: Fix ib_cache_setup_one error flow cleanup

When ib_cache_update return an error, we exit ib_cache_setup_one

instantly with no proper cleanup, even though before this we had

already successfully done gid_table_setup_one, that results in

the kernel WARN below.

Do proper cleanup using gid_table_cleanup_one before returning

the err in order to fix the issue.
