macintosh/via-macii: Fix "BUG: sleeping function called from invalid context"
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.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
