J. Bruce Fields b2c0cea6b1 nfsd4: check for negative dentry before use in nfsv4 readdir
After 2f9092e102 "Fix i_mutex vs.  readdir
handling in nfsd" (and 14f7dd63 "Copy XFS readdir hack into nfsd code"),
an entry may be removed between the first mutex_unlock and the second
mutex_lock. In this case, lookup_one_len() will return a negative
dentry.  Check for this case to avoid a NULL dereference.
