doio: fix shmread() on non-string buffers
- If the buffer is a reference, don't leak memory (or abort, on
debugging perls). The problem is that SvPOK_only() blindly turns off
some SV flags, but does not decrement any refcounts if ROK was on.
- If the buffer is tied, don't call FETCH. Conceptually, shmread() is a
bytestring assignment (from a shared memory segment to a scalar
variable), so it should only STORE. (This is also why most of the code
can be replaced by sv_setpvn().)
Fixes #22898.
