[PATCH] sh_eth: fix branch prediction in sh_eth_interrupt()

[Sergei Shtylyov]

IIUC, likely()/unlikely() should apply to the whole *if* statement's
expression, not a part of it  -- fix such expression in  sh_eth_interrupt()
accordingly...

Fixes: 283e38db65e7 ("sh_eth: Fix serialisation of interrupt disable with 
interrupt & NAPI handlers")

The patch is against DaveM's 'net-next.git' repo; I'm not sure if it should
be  targeted to the 'net.git' repo instead...
