spi: tegra210-quad: Move curr_xfer read inside spinlock
[ Upstream commit ef13ba357656451d6371940d8414e3e271df97e3 ]
Move the assignment of the transfer pointer from curr_xfer inside the
spinlock critical section in both handle_cpu_based_xfer() and
handle_dma_based_xfer().
Previously, curr_xfer was read before acquiring the lock, creating a
window where the timeout path could clear curr_xfer between reading it
and using it. By moving the read inside the lock, the handlers are
guaranteed to see a consistent value that cannot be modified by the
timeout path.
