description:
Avoid testing a possibly uninitialized errno value when using -exit.
Closes PR 44973 (change is a somewhat more principled equivalent of
the patch suggested there) although I cannot replicate the reported
behavior unless I explicitly prepare errno with a nonzero value before
the fts_read loop.
