David Sheets 07f0267561 fuse: fix time_to_jiffies nsec sanity check ...

commit 210675270c upstream.

Commit bcb6f6d2b9 ("fuse: use timespec64") introduced clamped nsec values
in time_to_jiffies but used the max of nsec and NSEC_PER_SEC - 1 instead of
the min. Because of this, dentries would stay in the cache longer than
requested and go stale in scenarios that relied on their timely eviction.
