In zonefs the file name in one of the two directories corresponds to the
zone number.
Here Alexey reported a possible integer overflow in zonefs_fname_to_fno(),
where the parsing of the zone number from the file name can overflow the
'long' data type.
Add a check for integer overflows and if the fno 'long' did overflow
return -ENOENT.
