niu: Fix missing unwind goto in niu_alloc_channels()
[ Upstream commit 8ce07be703456acb00e83d99f3b8036252c33b02 ]
Smatch reports: drivers/net/ethernet/sun/niu.c:4525
niu_alloc_channels() warn: missing unwind goto?
If niu_rbr_fill() fails, then we are directly returning 'err' without
freeing the channels.
Fix this by changing direct return to a goto 'out_err'.
