xfs: track cowblocks separately in i_flags
The EOFBLOCKS/COWBLOCKS tags are totally separate things, so track them with separate i_flags. Right now we're abusing IEOFBLOCKS for both, which is totally bogus because we won't tag the inode with COWBLOCKS if IEOFBLOCKS was set by a previous tagging of the inode with EOFBLOCKS. Found by wiring up clonerange to fsstress in xfs/017. Signed-off-by: Darrick J.
