tg3: driver sleeps indefinitely when EEH errors exceed eeh_max_freezes
The driver function tg3_io_error_detected() calls napi_disable twice,
without an intervening napi_enable, when the number of EEH errors exceeds
eeh_max_freezes, resulting in an indefinite sleep while holding rtnl_lock.
Add check for pcierr_recovery which skips code already executed for the
"Frozen" state.
