[4.2.x] Fixed #34612 -- Fixed QuerySet.only() crash on reverse relationships.
Regression in b3db6c8dcb5145f7d45eff517bcd96460475c879.
Thanks Ian Cubitt for the report.
This also corrected test_inheritance_deferred2() test which was
previously properly defined and marked as an expected failure but was
then wrongly adjusted to mask the lack of support for per-alias
deferral that was fixed by #21204.
Backport of 2cf76f2d5d1aa16acfadaf53db3d30128a34b088 from main
