[PATCH] nfs: do not deny execute access based on outdated mode in inode

[Donald Buczek <buczek@molgen.mpg.de>]

This patch fixes a problem, that a nfs4 client incorrectly denies
execute access based on outdated file mode (missing 'x' bit).
After the mode on the server is 'fixed' (chmod +x) further execution
attempts continue to fail, because the nfs ACCESS call updates
the access parameter but not the mode parameter or the mode in
the inode.

The access check based on the file mode is not required, because
the server already verified the clients rights.

Remove the test.
