usb_drv: Remove wait events for Nic
...
'alloc_skb' might now fail, the Nic component will then send a 'packet
available' signal and return. Fix broken SKB list implementation as well as
completely bogus initialization of SKBs.
Related to #778 .

Revert "usb_drv: Wait for IRQ on SKB exhaustion"
...
The fix overly influences gigabit ethernet performance (~200 MBit), so,
we need to investigate further.
This reverts commit aacb91f22aReopen #788 .

usb_drv: Wait for IRQ on SKB exhaustion
...
Do not use 'wait_event' when SKB-backend allocation fails, explicitly wait for
an interrupt, which in turn frees SKBs, instead.
Fixes issue #788
