spi: tegra210-quad: Protect curr_xfer clearing in tegra_qspi_non_combined_seq_xfer

Browse source

[ Upstream commit 6d7723e816 ]

Protect the curr_xfer clearing in tegra_qspi_non_combined_seq_xfer()
with the spinlock to prevent a race with the interrupt handler that
reads this field to check if a transfer is in progress.
