[ Upstream commit b28dbcb379e6a7f80262c2732a57681b1ee548ca ]
ssip_pn_open() claims the HSI client's port with hsi_claim_port(). When hsi_register_port_event() gets some error and returns a negetive value, the HSI client's port should be released with hsi_release_port().
Fix it by calling hsi_release_port() when hsi_register_port_event() fails.
