rsz: remove repair_setup_swap_sizeup_unbuffer regression test

Reverts the test added for issue #10210.  The UAF in prevPath()->pin()
requires specific post-CTS path-enumeration and allocator timing that
no minimal public testcase (Nangate45 small, ASAP7 gcd 3-tier VT,
ASAP7 aes_place.def at 22k components) reproduces under ASAN.  The
Tcl test therefore exercises the code path but does not actually
guard the regression -- reverting it would still pass.

Verification of the fix is via the original customer post-CTS ODB
under ASAN.  Keeping a non-guarding test file adds noise without
signal.
