Subject: [PATCH e2fsprogs] blkid: return cached info on either EPERM or EACCESS

This is for RH bug #448591: blkid command does not work for unprivileged users

commit 838f133c72a583eae67414368e46ee0303e0a51f made it so that
any error except EPERM would flush cached filesystem info, but
if I run blkid as an unprivileged user on F9, I get EACCES not
EPERM; I think that in this case, as well, we should continue.
