generic: check inode metadata on f{data}sync after power-cut
This patch adds case to test fsync and fdatasync with power-cuts.
The rule to check is:
1) fsync should guarantee all the inode metadata after power-cut,
2) fdatasync should guarantee i_size and i_blocks at least after
power-cut.
Note that, in XFS, it allocates more blocks when doing writes, so it
should close the file before fsync in order to get actual i_blocks
after power-cut. Or, it needs to do truncate the file with a
specific size to turn it off at the beginning.
