YueHaibing a069d4d98c tcp: restrict net.ipv4.tcp_app_win 
[ Upstream commit dc5110c2d959c1707e12df5f792f41d90614adaa ]

UBSAN: shift-out-of-bounds in net/ipv4/tcp_input.c:555:23
shift exponent 255 is too large for 32-bit type 'int'
CPU: 1 PID: 7907 Comm: ssh Not tainted 6.3.0-rc4-00161-g62bad54b26db-dirty #206
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014
Call Trace:
 <TASK>
 dump_stack_lvl+0x136/0x150

'maxwin' is int, shifting int for 32 or more bits is undefined behaviour.
