[PATCH] dmaengine: qcom: gpi: clean up the IRQ disable/enable in gpi_reset_chan()

[Dan Carpenter]

The calls write_lock/unlock_irq() disables and re-enables the IRQs.
Calling spin_lock_irqsave() and spin_lock_restore() when the IRQs are
already disabled doesn't do anything and just makes the code confusing.
