clear dst Hash on Hash#replace. [Bug #15358]
* hash.c (linear_copy): solve two issues on `Hash#replace`.
(1) fix memory leak
(1-1) don't allocate memory if destination already
has a memory area.
(1-2) free destination memory if src is NULL.
(2) clear transient heap flag if src is NULL. [Bug #15358]
