    Fix PR remote/9053: remove dead code on query packet size

    The code becomes dead as GDB evolves.  In 2003, Andrew Cagney post patch
    https://sourceware.org/ml/gdb-patches/2003-10/msg00511.html to add target
    read/write partial methods.  They support query buffer size when both
    OFFSET and LEN is zero, and it was used in avr-tdep.c and kod.c.  Then,
    Daniel added target_read_object_alloc and avr-tdep.c switches to use that
    in patch https://sourceware.org/ml/gdb-patches/2006-07/msg00009.html
    From then on, GDB on longer queries the buffer size, so the code
    returning packet size in remote_xfer_partial became dead.

    PR 17060 is duplicated of PR 9053, so I mention the latter in the
    ChangeLog entry.  Rebuild GDB with this patch.  OK to apply?
    I'll mark PR 17060 as duplicated once the patch is applied.

GDB on longer supports querying packet size (when LENGTH and OFFSET are zero),
and the corresponding code becomes dead.  Remove the dead code and close this
PR.
