    pfcache: fix misplaced endline in ext4_xattr_trusted_csum_list
    
    It is the fix for commit 00ebb1860eff ("pfcache: hide
    trusted.pfcache from listxattr")
    
    Else entries in list are not separated and getfattr fails:
    
    getfattr -d -m trusted /vz/root/110/testfile
    vz/root/110/testfile: trusted.pfcache�trusted.test: No such attribute
