Disable zfs_sync during oops/panic 

Minor update to ensure zfs_sync() is disabled if a kernel oops/panic
is triggered.  As the comment says 'data integrity is job one'.  This
change could have been done by defining panicstr to oops_in_progress
in the SPL.  But I felt it was better to use the native Linux API
here since to be clear.
