[PATCH v1 2/2] scsi: ufs: remove link_startup_again flow in ufshcd_link_startup

[Stanley Chu]

link_startup_again flow in ufshcd_link_startup() is not necessary
since currently device can be moved to "active" power mode during
resume flow by commit as below,

"scsi: ufs: set device as default active power mode during
initialization only"

Fixes: 7caf489b99a4 (scsi: ufs: issue link starup 2 times if device isn't active)
