Modified Files:
        src/sys/arch/alpha/alpha: interrupt.c

Log Message:
Don't use atomics to manipulate cpu_info::ci_intrdepth: it's modified
only in the interrupt service path by the owning CPU, at entry and exit.
Even if the r/m/w cycle of incrementing the value were interrupted, the
result would still be the same because the interrupting frame will have
completed its own symmetrical increment/decrement cycle upon return.
