Create bonded device test is failing due to improper initialisation in
bonded device configuration. which leads to crash while setting up queues.

The value of nb_rx_desc is checked if it is not in range of rx_desc_lim of
bonded device which fails.
This is due to "rx_desc_lim" is set to 0 as default value of bonded device
during bond_alloc().
Hence nb_rx_desc (1024) is > 0 and test fails.

Fix is to set the default values of rx_desc_lim of bonded device to
appropriate value.
