[PATCH -next] coresight: replicator: Fix missing spin_lock_init()

[Wei Yongjun]

The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.

This is detected by Coccinelle semantic patch.

Fixes: 0093875ad129 ("coresight: Serialize enabling/disabling a link device.")
