Subject: [PATCH] binfmt_misc: Fix binfmt_misc priority

This is resend of a patch that was sent couple of days ago, but I got
no response to it. No changes from previous version.

binfmt_misc: Fix binfmt_misc priority

Commit 74641f584da introduced a regression - binfmt_misc is now consulted
after binfmt_elf, which will unfortunately break ia32el. ia32 ELF binaries
on ia64 used to be matched using binfmt_misc and executed using wrapper. As
32bit binaries are now matched by binfmt_elf before bindmt_misc kicks in,
the wrapper is ignored.

The fix increases precedence of binfmt_misc to the original state.
