[ Upstream commit 909e22e05353a783c526829427e9a8de122fba9c ]

Fix a static code checker warning:
  fs/exportfs/expfs.c:171 reconnect_one() warn: passing zero to 'ERR_PTR'

The error path for lookup_one_len_unlocked failure
should set err to PTR_ERR.

Fixes: bbf7a8a3562f ("exportfs: move most of reconnect_path to helper function")
