ovl: Add comment on upperredirect reassignment
If memory for uperredirect was allocated with kstrdup() in upperdir != NULL
and d.redirect != NULL path, it may seem that it can be lost when
upperredirect is reassigned later, but it's not possible.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 0a2d0d3f2f291 ("ovl: Check redirect on index as well")
