[arm/tegra] dma: Interupt thread should be smp safe.
The interrupt thread handler have the static variable inside
a function. This is causing the corruption in the variale
when two processor execute the interrupt thread at same time
in smp mode.
Removing the qualifier static of a variable as this is not
required and also safe in smp mode.
