3.0-stable review patch. If anyone has any objections, please let us know.

From: Tushar Gohad <tgo...@mvista.com>
[ Upstream commit 4203223a1aed862b4445fdcd260d6139603a51d9 ]
Fix the min and max bit lengths for AES-CTR (RFC3686) keys.
The number of bits in key spec is the key length (128/256)
plus 32 bits of nonce.
This change takes care of the "Invalid key length" errors
reported by setkey when specifying 288 bit keys for aes-ctr.
