[PATCH stalld 21/52] tests: Remove if-wrappers around assert calls

Message-ID <[email protected]>
This is the second commit in a series introducing fail-fast semantics
to the test suite. Currently, several test scripts wrap assertion calls
in conditional blocks to guard subsequent execution steps.

Since the guarded test logic only makes sense when the initial assertion
passes, these conditional wrappers create unnecessary nesting. Once the
failure mechanism is updated to be immediately fatal in the next commit,
these protective conditional structures will become completely
redundant.

Removing the conditional structures and flattening the code flow across
the foreground, logging, pidfile, and starvation test scripts improves
overall readability and maintainability. Branches handling non-fatal
conditions such as skips or informational warnings have been preserved
in their original form.
