ACPI / event: remove unneeded NULL pointer check

Browse Source 
nla_data() cannot return NULL as it simply adds NLA_HDRLEN to the
passed pointer. The NULL pointer check is therefore superfluous.
Remove it.

  drivers/acpi/event.c:130 acpi_bus_generate_netlink_event() warn: can
  'event' even be NULL?
