fuse: fix time_to_jiffies nsec sanity check

Commit bcb6f6d2 ("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.

Fixes: bcb6f6d2
