macintosh/via-macii: Fix "BUG: sleeping function called from invalid context"

Browse Source 
[ Upstream commit d301a71c76 ]

The via-macii ADB driver calls request_irq() after disabling hard
interrupts. But disabling interrupts isn't necessary here because the
VIA shift register interrupt was masked during VIA1 initialization.
