[PATCH] orangefs: fix mode handling

[Christian Brauner <brauner@kernel.org>]

In 4053d2500beb ("orangefs: rework posix acl handling when creating new
filesystem objects") we tried to precalculate the correct mode when
creating a new inode. However, this leads to regressions when creating new
filesystem objects.

Even if we precalculate the mode we still need to call __orangefs_setattr()
to perform additional checks and we also need to update the mode of
ACL_TYPE_ACCESS acls set on the inode. The patch referenced above regressed
that. Restore that part of the old behavior and remove the mode
precalculation as it doesn't get us anything anymore.

    Hey Mike,
    
    The fix is pretty straightforward. I forgot to update the mode through
    __orangefs_setattr() and in the ACL_TYPE_ACCESS acl. This patch restores
    this and fixes the reported xfstest failure. I've pushed this out now.
    
    Thanks!
    Christian
