Zhang Xiaoxu 7e8436728e nfs4: Fix kmemleak when allocate slot failed 
If one of the slot allocate failed, should cleanup all the other
allocated slots, otherwise, the allocated slots will leak:

  unreferenced object 0xffff8881115aa100 (size 64):
    comm ""mount.nfs"", pid 679, jiffies 4294744957 (age 115.037s)
    hex dump (first 32 bytes):
