Dan Carpenter 760568c1f6 ksmbd: fix integer overflows on 32 bit systems 
commit aab98e2dbd upstream.

On 32bit systems the addition operations in ipc_msg_alloc() can
potentially overflow leading to memory corruption.
Add bounds checking using KSMBD_IPC_MAX_PAYLOAD to avoid overflow.

Fixes: 0626e6641f ("cifsd: add server handler for central processing and tranport layers")
