IB/ipath: Don't count IB symbol and link errors unless link is UP

Implement the ignoring of ibsymbol errors and linkrecover errors while
the link is at less than INIT (long needed), to get accurate counts.
Particularly an issue when doing non-IBTA DDR negotiation with chips
from vendors that do not support IBTA mode negotiation.  If the driver
is unloaded, and there is a delta, the adjusted counters are written
back to the chip, so they stay adjusted across driver reload.
