xfs: change the prefix of XFS_EOF_FLAGS_* to XFS_ICWALK_FLAG_
In preparation for renaming struct xfs_eofblocks to struct xfs_icwalk, change the prefix of the existing XFS_EOF_FLAGS_* flags to XFS_ICWALK_FLAG_ and convert all the existing users. This adds a degree of interface separation between the ioctl definitions and the incore parameters. Since FLAGS_UNION is only used in xfs_icache.c, move it there as a private flag.
