USB: musb_core: make disconnect and suspend interrupts work again

Browse Source 
Commit 1c25fda4a0 (usb: musb: handle irqs in the
order dictated by programming guide) forgot to get rid of the old 'STAGE0_MASK'
filter for calling musb_stage0_irq(), so now disconnect and suspend interrupts
are effectively ignored...
