USB: use IRQF_DISABLED for HCD interrupt handlers

Host controller IRQs are supposed to be serviced with interrupts
disabled.  This patch (as1026) adds an IRQF_DISABLED flag to all the
controller drivers that lack it.  It also replaces the
spin_lock_irqsave() and spin_unlock_irqrestore() calls in uhci_irq()
with simple spin_lock() and spin_unlock().

This fixes Bugzilla #9335.
