net: wwan: iosm: fix potential memory leaks in ipc_imem_init()

Browse Source 
commit c5d93b2c40 upstream.

The memory allocated in ipc_protocol_init() is not freed on the error
paths that follow in ipc_imem_init(). Fix that by calling the
corresponding release function ipc_protocol_deinit() in the error path.

Fixes: 3670970dd8 ("net: iosm: shared memory IPC interface")
