test: use mustSucceed in test-fs-read

This commit refactors the callback in test/parallel/test-fs-read.js
to use common.mustSucceed() instead of common.mustCall().

common.mustSucceed() is the preferred helper for standard error-first
callbacks that are expected to succeed, as it provides an explicit
check that the `err` argument is null. This improves the clarity
and robustness of the test.
