  hostfs: fix string handling in __dentry_name() (2025-01-11 01:37:44 -0500)

----------------------------------------------------------------
hostfs __dentry_name() fix

use of strcpy() with overlapping source and destination is a UB;
original loop hadn't been.  More to the point, the whole thing
is much easier done with memcpy() + memmove().
