USB: ehci: drop workaround for forced irq threading
Force-threaded interrupt handlers used to run with interrupts enabled, something which could lead to deadlocks in case a threaded handler shared a lock with code running in hard interrupt context (e.g. timer callbacks) and did not explicitly disable interrupts. Since commit 81e2073c175b ("genirq: Disable interrupts for force threaded handlers") interrupt handlers always run with interrupts disabled on non-RT so that drivers no longer need to do handle forced threading ("threadirqs"). Drop the now obsolete workaround added by commit a1227f3c1030 ("usb: ehci: fix deadlock when threadirqs option is used").
