softirq: Remove redundant h->action from preempt_count mismatch error

When a preempt_count mismatch is detected in handle_softirqs(), the
error message currently prints the softirq action handler (h->action).

However, as Thomas Gleixner pointed out, the action handler for a given
softirq vector is always a known, fixed function (e.g., run_timer_softirq
for TIMER_SOFTIRQ). Printing it provides zero diagnostic value. The real
issue typically lies in the functions invoked *within* that handler, not
the handler entry point itself.

Therefore, as suggested by Sebastian Andrzej Siewior, remove h->action
from the print statement entirely to clean up the error message.
