eth: r8152: try to use a normal budget
Mario reports that loading r8152 on his system leads to a:
netif_napi_add_weight() called with weight 256
warning getting printed. We don't have any solid data
on why such high budget was chosen, and it may cause
stalls in processing other softirqs and rt threads.
So try to switch back to the default (64) weight.
If this slows down someone's system we should investigate
which part of stopping starting the NAPI poll in this
driver are expensive.
