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

[ Upstream commit d301a71c76ee4c384b4e03cdc320a55f5cf1df05 ]

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.
