Description
This testcase uses Socket in blocking mode, and therefore
WOULD_BLOCK should not be accepted.
The logic was wrong anyway, because return value was tested
to be negative before testing with WOULD_BLOCK which is negative
as well.
Also replaced TEST_FAIL() macro with TEST_ASSERT_EQUAL() to
make the return code visible in test log.
