crypto: msm: Fix stress test failure

Stress test case scenarios involving a cipher operation for a large
packet (> 32KB) followed by a hash operation (of any data packet size)
fails, with the hash operation hanging.

The failure is due to the sps driver invoking the incorrect callback
for the subsequent hash operation. Instead of invoking the registered
hash operation callback,  it  invokes the previously registered cipher
operation callback.

The fix is to set the correct flag bits for the event when registering
the callback before invoking sps_register_event() and also removing
the SPS_EOT_EVENT flag when registering the sps_connect pipe information.
