The driver's error recovery reset sequence can take many seconds to
complete and only the critical sections are protected by rtnl_lock.
A recent change has introduced a regression in this sequence.
bnxt_remove_one() may be called while the recovery is in progress.
Normally, unregister_netdev() would cause bnxt_close_nic() to be
called and this would cause the error recovery to safely abort
with the BNXT_STATE_ABORT_ERR flag set in bnxt_close_nic().
Recently, we added bnxt_reinit_after_abort() to allow the user to
reopen the device after an aborted recovery. This causes the
regression in the scenario described above because we would
attempt to re-open even after the netdev has been unregistered.
Fix it by checking the netdev reg_state in
bnxt_reinit_after_abort() and abort if it is unregistered.
