[net] bnx2x: add missing napi deletion in error path

If the hardware initialization fails in bnx2x_nic_load() after adding
napi objects, they would not be deleted. A subsequent attempt to unload
the bnx2x module detects a corruption in the napi list.

Add the missing napi deletion to the error path.
