NFSv4: Fix free of uninitialized nfs4_label on referral lookup.

CVE-2022-49418

Description

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

Send along the already-allocated fattr along with nfs4_fs_locations, and drop the memcpy of fattr. We end up growing two more allocations, but this fixes up a crash as:
