nfs3_list_one_acl(): check get_acl() result with IS_ERR_OR_NULL

Browse source

commit 7a9e75a185 upstream.

There was a check for result being not NULL. But get_acl() may return
NULL, or ERR_PTR, or actual pointer.
The purpose of the function where current change is done is to "list
ACLs only when they are available", so any error condition of get_acl()
mustn't be elevated, and returning 0 there is still valid.
