[CVE-2011-1180] irda: validate peer name and attribute lengths

[Andy Whitcroft]

CVE-2011-1180
	Length fields provided by a peer for names and attributes may
	be longer than the destination array sizes.  Validate lengths to
	prevent stack buffer overflows.

The fix for this CVE has hit lucid and later via mainline and stable
updates.  Following this email is a patch for hardy, lucid/fsl-imx51,
and maverick/ti-omap4.  This is a simple cherry-pick of the upsteam change.

Proposing for hardy, lucid/fsl-imx51, and maverick/ti-omap4.
