net: libwx: fix number of Rx and Tx descriptors
commit 077ee7e6b13a2b6668196ed01a22023549e19381 upstream.
The number of transmit and receive descriptors must be a multiple of 128
due to the hardware limitation. If it is set to a multiple of 8 instead of
a multiple 128, the queues will easily be hung.
