linux-next: fix vector initialisation when !CONFIG_KGDB

From: Ben Dooks

It seems in the changes for adding CONFIG_KGDB that the ARM
trap initialisation has been turned off if the configuration
is not enabled. If CONFIG_KGDB is not set, the system locks
up as soon as the kernel turns the IRQs on for the first
time in init/main.c.

The fix is to remove the dependency on calling early_trap_init()
on CONFIG_KGDB, so that the vectors are initialised before
the init sequence enables the IRQs.
