ksmbd: Prevent integer overflow in calculation of deadtime
The user can set any value for 'deadtime'. This affects the arithmetic
expression 'req->deadtime * SMB_ECHO_INTERVAL', which is subject to
overflow. The added check makes the server behavior more predictable.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 0626e6641f6b ("cifsd: add server handler for central processing and tranport layers")
