[IA64] reset console_loglevel so INIT output always goes to console

Reset console_loglevel early in INIT handler.  Otherwise, if
it has been turned down (i.e., with "dmesg -n1"), the user may
see no effect at all from issuing an INIT.  We're never going
to run any more user code, so there won't be any opportunity for
anything to collect the output from the dmesg buffer.
