[PATCH 1/6] afs: Fix memory leak in afs_put_sysnames()

[David Howells]

From: Zhihao Cheng <chengzhih...@huawei.com>

Fix afs_put_sysnames() to actually free the specified afs_sysnames
object after its reference count has been decreased to zero and
its contents have been released.

Fixes: 6f8880d8e681557 ("afs: Implement @sys substitution handling")
