Subject: [PATCH] tile: remove compat_sys_lookup_dcookie declaration to fix
 compile error

With d8d14bd09cdd "fs/compat: fix lookup_dcookie() parameter handling" I
changed the type of the len parameter of the lookup_dcookie() syscall.

However I missed that there was still a stale declaration in arch/tile/..
which now causes a compile error on tile:

In file included from fs/dcookies.c:28:0:
include/linux/compat.h:425:17: error: conflicting types for 'compat_sys_lookup_dcookie'
fs/dcookies.c:207:1: error: conflicting types for 'compat_sys_lookup_dcookie'

Simply remove the declaration in the tile architecture, which is only a
leftover from before the different compat lookup_dcookie() versions have
been merged.
The declaration is now in include/linux/compat.h

The build error was reported by Fenguang's build bot.
