xfs_repair: clear bad flags in process_dinode_int

xfs_repair: clear bad flags in process_dinode_int

process_dinode_int() reports bad flags if dino->di_flags &
~XFS_DIFLAG_ANY - i.e. if any flags are set outside the known set.
But then instead of clearing them, it does flags &= ~XFS_DIFLAG_ANY
which keeps *only* the bad flags.  This leads to persistent,
unrepairable errors of the form:

"Bad flags set in inode XXX"

Fix this.

While we are at it, fix a couple lines which look like they used to
be continuation lines, but are no longer.
