Jakub Kicinski e407fceeaf eth: fbnic: remove the debugging trick of super high page bias
Alex added page bias of LONG_MAX, which is admittedly quite
a clever way of catching overflows of the pp ref count.
The page pool code was "optimized" to leave the ref at 1
for freed pages so it can't catch basic bugs by itself any more.
(Something we should probably address under DEBUG_NET...)

Unfortunately for fbnic since commit f7dc3248dc ("skbuff: Optimization
of SKB coalescing for page pool") core _may_ actually take two extra
pp refcounts, if one of them is returned before driver gives up the bias
the ret < 0 check in page_pool_unref_netmem() will trigger.

While at it add a FBNIC_ to the name of the driver constant.

Fixes: 0cb4c0a137 ("eth: fbnic: Implement Rx queue alloc/start/stop/free")
