net/core/sock.c: quiet sparse noise
In sock_getsockopt the symbol 'lv' is declared as an
unsigned int type, probably due to sizeof returning a
size_t which is really an unsigned int.
This produces a sparse warning for SO_PEERNAME due to
the sock->ops->getname() call:
warning: incorrect type in argument 3 (different signedness)
expected int *sockaddr_len
got unsigned int *<noident>
Quiet the warning my changing the type of 'lv' to an int.

Applied to net-next-2.6, thanks.
