[PATCH] fix system_state checking in early_ioremap

[Dave Young]

Since below commit earlyprintk=efi,keep does not work any more with a warning
in mm/early_ioremap.c: WARN_ON(system_state >= SYSTEM_RUNNING):
commit 69a78ff226fe ("init: Introduce SYSTEM_SCHEDULING state")

Reason is the the original assumption is SYSTEM_BOOTING equal to
system_state < SYSTEM_RUNNING. But with commit 69a78ff226fe it is not true
any more. Change the WARN_ON to check system_state >= SYSTEM_RUNNING instead.
