scsi: hisi_sas: Delete unused lock in hisi_sas_port_notify_formed()
Currently spinlock hisi_hba->lock is used by both interrupts and threads
which requires the use of spin_lock_irqsave()/spin_unlock_irqrestore().
However, some places still use spin_lock()/spin_unlock(). Reviewing the
code revealed that it is unnecessary to use hisi_hba->lock in the function
hisi_sas_port_notify_formed() which is the only place that uses the
spinlock in interrupt context. So delete unused lock in
hisi_sas_port_notify_formed().
