$test_prereq is used as a named parameter of the function test_skip,
which uses it to determine if a test needs to be skipped due to
missing prerequisites.  Checking and exporting its input parameter
only after it succeeded probably won't do any good.

Anyway, didn't e0316695ec3 (test-lib: don't check prereqs of test
cases that won't be run anyway, 2019-11-12) already solve the
issue?
