[PATCH] scsi: ufs: Remove redundant vops NULL check and trivial wrapper

[Chanwoo Lee]

ufshcd_variant_hba_init/exit() check 'if (!hba->vops)' before
calling vops wrappers, but the wrappers already do NULL check
internally. Remove the redundant checks. Also remove
ufshcd_variant_hba_exit() entirely since it only wraps
ufshcd_vops_exit() with no added value.
