Shawn Nematbakhsh 369fbaf052 npcx: shi: Avoid 'unexpected state' console spam
If SHI finds itself in an unexpected state, we may try to print an error
message for each IBF / IBHF interrupt, which is excessively spammy and
may even lead to EC watchdog. Avoid console spam by not duplicating IBF
/ IBHF / IBEOR error prints, if our state doesn't change.

BUG=chrome-os-partner:54502
BRANCH=None
TEST=Manual on gru. Verify only one print is seen when SHI fails due to
missed initialization.
