usb: gadget: gsi: Avoid spinlock lockup
In this case gsi_ctrl_clear_cpkt_queues function is called
which is holding spinlock and in the meantime dwc3_interrupt
occurred on same CPU which in turn is calling gsi_ctrl_clear_cpkt_queues
function and it is trying to acquire the same spinlock causing
deadlock.
This change disables the interrupts when spinlock is acquired
in gsi_ctrl_clear_cpkt_queues function.
