net/bonding: fix values of descriptor limits

test_create_bonded_device 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.
Receive the values from slaves configuration like done for other
existing slave configuration
