param: update drivers/char/ipmi/ipmi_watchdog.c to new scheme
This is one of the most interesting users of module parameters in the
tree, so weaning it off the old-style non-const module_param_call
scheme is a useful exercise.
I was confused by set_param_int/get_param_int (vs. the normal
param_set_int and param_get_int), so I renamed set_param_int to
set_param_timeout, and re-used param_get_int directly instead of
get_param_int. I also implemented param_check_wdog_ifnum and
param_check_timeout, so now the ifnum_to_use and timeout/pretimeout
parameters can just use plain module_param().
