RDMA/bnxt_re: Move device to error state upon device crash

Browse source 
When the L2 driver detects a device crash or device undergone reset, it
invokes a stop callback to recover from error.

The current RoCE driver doesn't recover the device. So move the device to
error state and dispatch fatal events to all qps Release the MSIx vectors
to avoid a crash when L2 driver disables the MSIx.  Also, check for the
device state to avoid posting further commands to the HW.
