cifs: Fix integer overflow while processing acdirmax mount option
[ Upstream commit 5b29891f91dfb8758baf1e2217bef4b16b2b165b ]
User-provided mount parameter acdirmax of type u32 is intended to have
an upper limit, but before it is validated, the value is converted from
seconds to jiffies which can lead to an integer overflow.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 4c9f948142a5 ("cifs: Add new mount parameter "acdirmax" to allow caching directory metadata")
