[PATCH 01/30] staging: wilc1000: added complete() call for error scenario in handle_key()

[Ajay Singh <ajay.kathat@xxxxxxxxxxxxx>]

During memory allocation failure in handle_key() the complete() was not
called for comp_test_key_block event. So now added the code to call
complete() for event during error scenario.
