libmount: hide details about failed search in fstab/mtab
The current code returns -errno when not found "mount /foo" in fstab
and mtab does not exist (or /etc/mtab points to non-mounted /proc).
This is problem because the return value is too low-level and maybe
misinterpreted by top level code. It's better to always return
MNT_ERR_NOFSTAB when not found in fstab/mtab.
