[Bug-tar] [PATCH] fix overflow in code_ns_fraction()

[Andreas Dilger]

If the on-disk nanoseconds count happens to exceed 999,999,999 then  
code_ns_fraction() will overflow the 9-character array and segfault.   
While this shouldn't happen normally, it can happen due to corruption  
of the on-disk data.  If the ns field is larger than 999,999,999  
truncate it to this value

Cheers, Andreas
