spi: tegra210-quad: Fix iterator outside loop
[ Upstream commit 2449d436681d40bc63ec2c766fd51b632270d8a7 ]
Fix warn: iterator used outside loop: 'xfer'. 'xfer' variable contain
invalid value in few conditions. Complete transfer within DATA phase
in successful case and at the end for failed transfer.
