[PATCH] Fix wrong flag ASSERT in xfs_attr_shortform_getvalue

[Eric Sandeen <sandeen@xxxxxxxxxx>]

This ASSERT is testing an if_flags flag value against
a di_aformat enum value.  di_aformat is never assigned
XFS_IFINLINE.

This happens to work for now, because XFS_IFINLINE has
the same value as XFS_DINODE_FMT_LOCAL, and that's tested
just before we call this function.

However, I think the intention is to assert that we have
read in the data, i.e. XFS_IFINLINE on if_flags, before
we use if_data.  This is done in other places through the
code as well.

Note, maybe it should be:

        ASSERT(args->dp->i_d.di_aformat == XFS_DINODE_FMT_LOCAL);

but there is an if statement in the caller which assures that,
so as the code stands that would seem pointless.  I'm not 100%
sure what the original intent was, though, so ...
