ata: fix "ering" sysfs time printing ...
The sysfs file for the libata error handling has multiple issues
in the way it prints time stamps:
* it prints a 9-digit nanosecond value using a %06lu format string,
which drops some leading zeroes
* it converts a 64-bit jiffes value to a timespec using
jiffies_to_timespec(), which takes a 'long' argument, so the
result is wrong after a jiffies overflow (49 days).
* we try to avoid using timespec because that generally overflows
in 2038, although this particular usage is ok.
This replaces the jiffies_to_timespec call with an open-coded
implementation that gets it right.
