scsi: ufshcd: release resources if probe fails

If ufshcd pltfrm/pci driver's probe fails for some reason then ensure that
scsi host is released to avoid memory leak but managed memory allocations
(via devm_* calls) need not to be freed explicitly on probe failure as
memory allocated with these functions is automatically freed on driver
detach.
