Subject: [PATCH] Replace _spin_trylock with spin_trylock in the IRQ variants to use __cond_lock

spin_trylock_irq and spin_trylock_irqsave use _spin_trylock, which does not
use the __cond_lock wrapper annotation and thus does not affect the lock
context; change them to use spin_trylock instead, which does use __cond_lock.
