dwc3-msm: Fix unbalanced IRQ wake disable for non-PDC based USB interrupts

In current code driver making "uirq->enable" flag to true for both
wakeup irq enable case and wakeup irq disable case. Due to this
non pdc irqs are going to disable path twice and reporting
unbalanced IRQ wake disable error.

Fix this by marking uirq->enable flag to false in wakeup disable case.
