staging: wilc1000: replace sem_test_disconn_block with a completion

Semaphore sem_test_disconn_block is used to signal completion of its
host interface message. Since the thread locking this semaphore will
have to wait, completions are the preferred mechanism and will offer
a performance improvement.
