tests/qtest/e1000e-test: Check qemu_recv() succeeded

The e1000e_send_verify() test calls qemu_recv() but doesn't
check that the call succeeded, which annoys Coverity. Add
an explicit test check for the length of the data.

(This is a test check, not a "we assume this syscall always
succeeds", so we use g_assert_cmpint() rather than g_assert().)

Fixes: Coverity CID 1432324
