colibri_t30: fix usb ethernet functionality

Since commit aa7a648747d8c704a9a81c9e493d386930724e9d
("net: Stop including NFS overhead in defragment max") the following
has been reproducibly observed while trying to transfer data over TFTP:

Load address: 0x80408000
Loading: EHCI timed out on TD - token=0x8008d80
T EHCI timed out on TD - token=0x88008d80
Rx: failed to receive: -5

This patch fixes this by upping our maximal de-fragmentation aka IP
packet size again.
