docs: admin-guide: sysctl: fix details of struct dentry_stat_t



Commit c8c0c239 moved struct dentry_stat_t to fs/dcache.c but
did not update its location in Documentation, so update that now.
Also change each struct member from int to long as done in
commit 3942c07c.

Fixes: c8c0c239 ("fs: move dcache sysctls to its own file")
Fixes: 3942c07c ("fs: bump inode and dentry counters to long")
