Roman Smirnov 64ddb14fd0 cifs: fix integer overflow in match_server()
[ Upstream commit 2510859475 ]

The echo_interval is not limited in any way during mounting,
which makes it possible to write a large number to it. This can
cause an overflow when multiplying ctx->echo_interval by HZ in
match_server().

Add constraints for echo_interval to smb3_fs_context_parse_param().

Found by Linux Verification Center (linuxtesting.org) with Svace.

Fixes: adfeb3e00e ("cifs: Make echo interval tunable")
