[CVE-2011-2493] ext4: init timer earlier to avoid a kernel panic in __save_error_info

[Andy Whitcroft]

CVE-2011-2493
	No description in the CVE.  It appears this is a security issue
	as an external USB stick could be crafted to trigger an oops
	on insertion.

This issue was only introduced in v2.6.36-rc1 so maverick and earlier are
not affected.  The fix has already hit oneiric via mainline.  Following
this email is a single patch for natty and natty/ti-omap4 it is a clean
cherry-pick from mainline.

Proposing for natty and natty ti-omap4.
