[PATCH] xfs_logprint: handle the log split of inode item correctly

[Hou Tao <houtao1@huawei.com>]

It is possible that the data fork or the attribute fork
of an inode will be splitted to the next log record, so
we need to check the count of available operations
in the log record and calculate the count of skipped
operations properly.
