There is issue when firmware is being updated, but mxt_remove()
is called to remove driver, because at very beginning IRQ is disabled
so that firmware can't proceed, thus cause driver to hang.

This patch by move disable_irq() after remove of mxt_fw_attr_group in
mxt_remove() to address this issue.
