zink: modify some buffer mapping behavior for buffer replacement srcs

Browse Source 
if the src for a replace_buffer call is mapped after replacement:
* avoid clearing access flags
* update valid range

the pointer access here is always safe because the only case in which
this scenario can occur is if tc is forced to sync immediately after
creating a replaceent buffer, and the replacement buffer's lifetime
will always be exceeded by the lifetime of the real buffer
