[PATCH 1/2] xfs: project id inheritance is a directory only flag

[Dave Chinner]

From: Dave Chinner <dchinner at redhat.com>

xfs_set_diflags() allows it to be set on non-directory inodes, and
this flags errors in xfs_repair. Further, inode allocation allows
the same directory-only flag to be inherited to non-directories.
Make sure directory inode flags don't appear on other types of
inodes.

This fixes several xfstests scratch fileystem corruption reports
(e.g. xfs/050) now that xfstests checks scratch filesystems after
test completion.
