e1000e: Fix incorrect debug warning
Doing 'WARN_ON(preempt_count())' was horribly horribly wrong, and would
cause tons of warnings at bootup if PREEMPT was enabled because the
initcalls currently run with the kernel lock, which increments the
preempt count.
At the same time, the warning was also insufficient, since it didn't
check that interrupts were enabled.
The proper debug function to use for something that can sleep and wants
a warning if it's called in the wrong context is 'might_sleep()'.
