scsi: ufs: core: Move the ufshcd_device_init(hba, true) call
ufshcd_async_scan() is called (asynchronously) only by ufshcd_init().
Move the ufshcd_device_init(hba, true) call from ufshcd_async_scan()
into ufshcd_init(). This patch prepares for moving both scsi_add_host()
calls into ufshcd_add_scsi_host(). Calling ufshcd_device_init() from
ufshcd_init() without holding hba->host_sem is safe. This is safe
because hba->host_sem serializes core code and sysfs callbacks. The
ufshcd_device_init() call is moved before the scsi_add_host() call and
hence happens before any SCSI sysfs attributes are created.
Since ufshcd_device_init() may call scsi_add_host(), only call
scsi_add_host() from ufshcd_add_scsi_host() if the SCSI host has not yet
been added by ufshcd_device_init().
