[PATCH] autofs: fix compilation on hosts without CONFIG_COMPAT

[Alexander Graf]

When compiling 3.3-rc5 on arm, I get the following compilation error:

  fs/autofs4/inode.c: In function 'autofs4_fill_super':
  fs/autofs4/inode.c:228:2: error: implicit declaration of function 'is_compat_task' [-Werror=implicit-function-declaration]

which was introduced by commit a32744d4a. On platforms that don't define
CONFIG_COMPAT, using is_compat_task() is not necessarily defined. So
let's just not use it there.

Sorry if this was already fixed elsewhere - I couldn't find a patch for it, but
my LKML searching skills are slightly limited :)
