[XFRM]: alg_key_len should be unsigned to avoid integer divides
Eric Dumazet [Sun, 13 Jan 2008 05:30:23 +0000 (21:30 -0800)]
alg_key_len is currently defined as 'signed int'. This unfortunatly
leads to integer divides in several paths.

Converting it to unsigned is safe and saves 208 bytes of text on i386.
